How many places in the middle of the design are detrimental to the result, but end up with a finished product with an improved melting point?

What does it mean?

This shows that there are steps in the process that greatly help to increase the melting point of the finished product!

The manufacturing process of K03A is too complicated. In some places, harmful and beneficial conclusions can be drawn directly by using the "Law of Cause and Effect", and in some places, it may involve microstructure issues, and no conclusions can be drawn at all.

So logical analysis is also very important.

Zhao Yi suddenly thought of a question, "If the problem in the design is corrected and the 'harmful' and 'useless' parts are removed, will the finished product have a higher melting point and better performance?"

"You can try it!"

"However, let's wait until all the tests are over..."

The test being done is also very important. The strength test is more complicated than the melting point test, and some high-voltage equipment is used as an auxiliary method. The test lasted for two hours, and finally came to a conclusion--

The strength of the finished product is reduced by about one percent.

The strength is directly related to the addition of rhenium element. Metal rhenium is soft, and if it is not perfectly combined with other elements in the alloy, it is likely to reduce the strength of the final product.

However, a one percent decrease in strength is still within the acceptable range. At the same time, the decrease in strength also clearly shows that the rhenium element is not perfectly combined with other elements, which means that there is still room for improvement in the finished product.

Whether it is strength, melting point or corrosion resistance, there is room for improvement.

After the performance test of the finished product, there will be an internal meeting, the content of which is to summarize the experimental experience and explain the next step of the experimental plan.

He Guilin also participated this time. He is a representative of 307 Steel Plant and is not in Zhao Yi's R&D team, but the R&D team cannot do without the support of 307 Steel Plant. question.

"Professor Shen's design is great!"

Zhao Yi affirmed the design when he came up, "The melting point has increased by about [-] degrees, and the strength has decreased, but it is still acceptable. These two materials must be well preserved."

"Do you want to publish the results?" He Guilin asked suddenly.

Zhao Yi glanced at him strangely, and asked in confusion, "Didn't the research and development just start? This is our first experiment." What he meant was that it was only the first experiment, and even if the performance of the finished product improved, it was completely negligible. No results.

Several people in the R&D team were very indifferent.

Although the melting point of the finished product has been improved, it is indeed the product of the first experiment. They also know that Zhao Yi's goal is to manufacture the world's most advanced nickel-iron alloy with the highest melting point that can be assembled into the top turbine engine. The target must exceed [-] Baidu.

Now it only exceeds [-] Baidu, and the gap is still relatively large.

"Then the next experiment..."

Wang Zhifang asked suddenly, "Is it Li Rongmao's? Or Hong Tao?"

Both Li Rongmao and Zhang Hongtao were eager to try.

Wang Zhifang also took advantage of the opportunity and took out a design, which seemed to be explained on the table. Everyone else knew that it was his design. Only Wang Zhifang did not explain it at the last meeting.

Zhao Yi felt that Wang Zhifang's face should be taken care of, but after thinking about it, he still didn't waste time. He said, "Academician Wang, the plan can't keep up with the changes. The previous plan was for everyone to come up with a design and do four experiments in a row. But now Professor Shen The design has improved the performance of the finished product. We can see from the final test data that there is a lot of room for improvement in this finished product.”

"So I have an idea, let's conduct a detailed demonstration of Professor Shen's design together, demonstrate every step, and finally come up with a complete set of plans."

"Next experiment, let's try."

When other people heard Zhao Yi's thoughts, they looked at me and I looked at you, and their expressions were somewhat surprised. They thought they would do experiments designed by others, but they didn't expect that Zhao Yi's idea was to continue to demonstrate Shen Binghe's design, However, the experimental results show that Shen Binghe's design has some brilliant points. It is indeed a good direction to find out the advantages of his design and then make other corrections.

Li Rongmao and Zhang Hongtao secretly felt it was a pity. They also hoped that their designs could be put into experiments to see how the finished products would look like, but it seems that they don't need it anymore?

They could find no reason to object.

If you think purely from the perspective of research and development, what Zhao Yi said is the best choice.

Wang Zhifang put away the design silently with gloom. He really hoped that the research and development would go smoothly, but he expected to be led by himself, at least by his own design. None of the 'playing opportunities'.

What can I say now?

Wang Zhifang didn't speak at all, but expressed his emotions in silence. He couldn't say anything against it, and it was really depressing to support it.

What Zhao Yi said is indeed a very good direction. From a neutral point of view, everyone supports it. The next step is to conduct an argument. The argument is to study Shen Binghe's design in detail to see where it may play a positive role and where May have the opposite effect.

Zhao Yi did not directly participate in the argumentation, but as a "principal judge". He is like an impartial adjudicator, and he does have decision-making power if he does not participate in the discussion.

In fact, Zhao Yi roughly understood a few points in his heart.

Some modifications that are harmful to the finished product, he has already recorded them all, and he must go directly to them. It is too difficult to turn harmful into beneficial, so he simply gave up.

Some modifications are 'useless', which can still be demonstrated. Let everyone freely play, speak freely, and express their own ideas, and maybe the uselessness can be turned into a benefit.

This time even He Guilin participated in the demonstration, and his participation is also very crucial, because he has been doing research on nickel-iron alloys and has also done the direction of adding new elements, and he can give some experimental data.

Most of the experimental data are failures, but they are of certain reference value.

The argument in the conference room lasted until eight o'clock in the evening, and each issue was discussed for a long time. Finally, Zhao Yi checked the time and decided to end the meeting, "Today is too late, remember to sort out the data tomorrow, and continue in the afternoon. Our next experiment will be at least It's next week."

He briefly explained his work and ended the discussion for the day.

……

Aviation research and development base, Kunlun engine group.

Some time ago, the 307 Steel Plant announced that the K03A melting point performance was improved, and the engine group was also prepared for this. Last week they got a few finished products for testing, and then a lot of work from the R&D team came.

The turbine group needs to study and design a more suitable blade matching scheme according to the improvement of the material performance of the turbine blades; the power group needs to adjust the energy output of the combustion chamber in order to increase the maximum power of the engine from the root.

and many more.

The work of the power group is in charge of the team leader Zhou Kai and the veteran technician Gao Yaxin.

Zhou Kai and Gao Yaxin are technicians with rich experience. Based on the performance parameters of the new K03A tested and fed back, they conducted detailed research on the fuel input control, air pressure, and partition design of the combustion chamber, and finally came up with a set of very Reasonable solution.

After the plan was submitted, Zhang Gangchuan, the person in charge of the engine group, asked the two to go to the conference center to make a report. After listening to the report, several senior technicians and leaders of the engine group felt that there was no problem with the design, and then directly signed and approved it.

Zhou Kai and Gao Yaxin walked out of the conference room together, with relaxed smiles on their faces.

Zhou Kai said, "The performance of K03A has been improved, and our supporting equipment has also been improved. The power of the entire engine will definitely be greatly improved. We can also be regarded as contributing to the improvement of performance."

Gao Yaxin nodded and said, "The design has been passed directly, and the next step is to wait for the factory to produce new samples."

"Yes."

Zhou Kai felt very relaxed when he said that. The work of their power group is really easy. When they have something to do, they can work on the design, and they can stay leisurely at other times. There is no more leisurely team.

He thought about it and suddenly talked about Wang Zhiguo, "Xiao Wang has also worked hard. It is really interesting to go to the capital and design a combustion chamber control scheme with turbine blades at 1700 degrees. Xiao Wang's level is still insufficient, and it is meaningless to do this design." , it's hard for him..."

"Yes."

Gao Yaxin also sighed, and he added, "He is still young. If I were younger, I would go for him. It is also good to see Academician Zhao himself. I saw the photo posted by Xiao Wang. He and Zhao The academicians have a group photo." He suddenly felt a little envious as he spoke.

Although taking a photo with Zhao Yi is not a big deal, it is also used to brag. Zhao Yi's reputation is more obvious than that of the upper class. Others will definitely take a high look when they see the photo. Research can be related to Zhao Yi. It seems that It also became taller.

Zhou Kai shook his head amusedly and asked, "Why don't you go too? Anyway, there's nothing to do recently."

"No, no, no."

Gao Yaxin quickly shook his head, "I'm the one with the family, I can't help you if I go, let Xiao Wang come, young people just need experience."

"It's good for young people to exercise." Zhou Kai also nodded, "Even if the design is useless, it's just learning. Xiao Wang's level is still a little lower, and he can lay the foundation for future work!"

"Yes!"

Gao Yaxin nodded with a sigh, as if both of them were thinking about Wang Zhiguo, but in fact, they just didn't want to make a trip to do research that was 'meaningless'.

Chapter 437 No one is more rigorous than you

Metal Materials Laboratory.

For several days, the R&D team has been demonstrating Shen Binghe's design. The process of demonstration is full of data, imagination and debate. There is no 100% sure answer in the demonstration of the manufacturing design of alloy materials. For example, whether a certain step affects the performance of the final product If it is beneficial, it can only be judged by experience and theoretical imagination. Needless to say, experience, there are too few references for brand-new research, and they can only use a small amount of data to illustrate the situation.

Everyone's ideas are different, but the theory can also say several tricks. When arguing about issues, it feels like a philosophical discussion rather than a research on alloy materials.

But what can be seen is that everyone is working hard to do a good job in the design. They are all members of the R&D team. Really achieving great results not only represents the progress of technology, but also reflects the progress of each of them. On the resume, write down a very strong stroke.

The same goes for Wang Zhifang.

Although he is already an academician of the Academy of Engineering, and there is no room for promotion in his rank, he also hopes that his scientific research resume will show the world's top research results.

This time it was rare for him to agree with Zhao Yi. They both felt that starting from Shen Binghe's design was a very good research and development direction, because experiments had proved that Shen Binghe's design was very desirable.

The only regret is that his design can only be placed in a backpack.

Wang Zhifang brings his designs with him at all times, and his mentality is the same as that of others. He hopes that his designs can be applied to experiments to see what kind of finished products he can produce. What others don't know is that he continues to To modify the design, considering the reason why Shen Binghe's design was adopted, he also specially made a set of "full of loopholes" design.

Of course, he just carried it with him and would not take it out on his own initiative. He only vaguely expected that Zhao Yi would bring up a "design with many problems" again. Say, "Isn't that an entry-level design? I just made one!"

In order to make this design more "introductory", he continued to modify and improve it, and deleted the process of "using rich experience" and "can withstand rigorous demonstration" and replaced it with "very controversial steps". .

"Unfortunately, it's no longer available!"

"No matter how much you modify it, it's useless. Even if you really want to choose another design, it's impossible to take this one out!" Wang Zhifang thought with some regret.

……

The argument went on for a week.

One week is relatively long, because Shen Binghe's design has been put into experiments, and finished products with improved performance have been produced. Even if the demonstration is carried out step by step, it will normally not exceed three days.

It can also be seen that the research and development team attaches great importance to the demonstration.

At the beginning, the speed was relatively fast. Zhao Yi quickly eliminated several steps that 'had a negative impact on the performance of the finished product', and the rest were 'uncertain' and 'no impact on performance' steps.

Some of these controversial places even have to argue for a whole day, which is a relatively long time.

Actually, it's normal.

If you consider the cost of an experiment, it is nothing to argue for a few days to make the design more rigorous.

Another reason is that there is plenty of time. When the R&D team did the first experiment, they were not fully prepared. The main reason is that the procurement of experimental materials did not keep up. For example, the materials required for alloy research and development are impossible to have in the market. Those sold are all purchased from specialized factories, and some need to purchase imported products.

A lot of materials used in the first experiment were shipped by He Guilin’s team from 307 Steel Factory. There will be many experiments to be done later, and it is impossible for all of them to be provided by 307 Steel Factory.

So still have to wait.

Two weeks later, everything was ready, and the R&D team immediately started the second experiment.

The 307 steel plant, the metal material laboratory, the metal composite material laboratory, the factory, and He Guilin's team started efficient operations in coordination. The initial materials were produced in the 307 steel plant and were quickly transported to the metal material laboratory.

After simple testing and processing, the owner of the R&D team and He Guilin's team went to the supporting factory of the metal composite material laboratory to conduct experiments.

With the experience of the first experiment, the second speed is very fast.

It took less than two days to reach the final step. Zhao Yi once again decided to divide it into two parts, one using conventional cold rolling technology, and the other using more complicated slow cooling technology.

After the two finished products cooled to the normal temperature, they were quickly transported to the metal material laboratory. The R&D team and He Guilin's team also went to the metal material laboratory to conduct the final inspection of the two finished products. The main force in charge of the inspection is still Li Rongmao , Zhang Hongtao.

Shen Binghe also participated this time.

Shen Binghe's actual operation level is still much lower, but the research and development team has been doing research together for a long time, and the relationship between several people who are about the same age is very good. Others also intend to help Shen Binghe and give him the opportunity to exercise his operation ability.

Zhang Hongtao took the initiative to pass the high temperature gun to Shen Binghe, "Binghe, come and try!"

"The temperature of this thing is too high, please be careful!"

"If not, let me do it? You have to control the temperature and pay attention, we are doing testing, not letting you melt it."

"..."

The testing process is slightly informal, but it doesn't matter because the material is divided into several parts.

soon.

Li Rongmao's results came out, and he exclaimed, "It's over 1600 degrees!"

"Really?"

"That's right!"

"Great!"

The few people standing in the distance immediately became excited. They stared at the past with wide-eyed expressions on their faces full of anticipation.

At this moment, Shen Binghe shouted, "1570 degrees!"

The one he tested was cold-rolled, and the lower melting point was expected.

Soon Li Rongmao also shouted, "Around 1620!" His tone was obviously excited.

"Whoo~~~"

After hearing this number, everyone gasped. They never expected that just the second experiment would increase the melting point of the finished product by another [-] degrees based on the results of the first experiment.

"1620 degrees!"

"This should be the melting point of the world's top nickel alloy, right? Far beyond the performance of the turbine blades of the turbine engines imported from country E."

"It's almost catching up with the data of the top fighter jets in country M."
