The latest top-level fighter jet developed by country M uses the most cutting-edge technology. According to the published engine data, the melting point of the turbine blade material is above 2000 degrees Celsius, which is more than 1700 degrees Celsius.

It is also the only nickel alloy material in the world with a confirmed melting point above 1600 degrees Celsius.

Now the newly researched finished product has a melting point exceeding 1600 degrees Celsius, which means it exceeds all other nickel alloy materials, at least within the disclosed range, and is the nickel alloy material with the second highest melting point in the world, but one point that must be considered is that M According to the data released by the Chinese company, the proportion of rhenium in the nickel alloy is about [-]%, while their second test plan, the proportion of rhenium in the theoretically manufactured finished product is only [-]%.

The rhenium element accounts for six percent, and its melting point is 1700+ degrees Celsius.

Rhenium accounts for 1620 percent and has a melting point of [-] degrees Celsius.

The proportion of rhenium element shows the composition of the material, which also shows the technical difficulty and material cost. The material they developed has a small proportion of rhenium element, which means that the cost is relatively low, and the melting point will not be much lower, which also shows the technical difficulty. not weaker than the former.

"Ours is better. Its melting point is 1620, which is only a hundred points short, but in terms of element ratio, there are two points less rhenium!"

"Our finished product can make the performance of rhenium better!"

"This can already be said to be the most advanced and the best in performance, right? And it is enough to meet the world's top aero engine needs!"

"It's really a great result!"

"If we announce it now, will it cause an international sensation?"

"..."

Everyone is discussing excitedly.

Testing continues.

Zhang Hongtao, Li Rongmao, He Guilin, and Shen Binghe tested the strength of the finished product together. After more than two hours of rigorous testing, they announced together, "The strength has not changed from the original one, and it has improved compared to the last experiment."

"very successful!"

There is no need to add the last comment.

The melting point of the finished product is increased, but the strength is not reduced, indicating that the rhenium element is perfectly embedded in the alloy composition.

Everyone immediately fell into a new round of excitement.

Zhao Yi's expression is very calm, the experimental results are not unexpected, the performance of the finished product is definitely improved, because he deleted those steps that are harmful to the performance of the finished product, even if there is no follow-up discussion, the performance of the finished product will not It will definitely increase, but the specific increase is uncertain.

After this experiment, he got a few more conditions.

Among them is a newly demonstrated step, which is still harmful to the performance of the finished product. The harmful step will be deleted in the next experiment, and then continue to demonstrate those steps that are not helpful and uncertain.

Zhao Yi made a decision, and quickly called everyone together to tell the next step.

"Still continuing the argument?"

"Academician Zhao, the strength has not decreased, which means that the embedding of the rhenium element is perfect, and this can already be regarded as a finished product."

"It can't be counted, it's a finished product!"

"I don't think there is any need to continue, right? Now that this result is released, it will cause an international sensation."

Zhao Yi shook his head, frowned and said, "Your requirements are too low, right? We have just done two experiments, and there must be a lot of room for improvement. I hope that the melting point of the finished product should reach at least [-] degrees."

"..."

"..."

Others, if you look at me and I look at you, they can only shake their heads and express their agreement with a wry smile.

It is the first time that Zhao Yi clearly stated that the research and development goal is to increase the melting point to above [-] baidu, and they also hope to achieve this goal, which is truly the number one in the world, but at the same time they always feel that it is very unrealistic. It is an indisputable fact that China's advanced alloy material technology lags behind foreign countries, not only in the field of aero engines, but also in other fields.

Many things can be seen from the rare earth issue.

China is a rare earth superpower and exports a series of rare earth products, but most of them are foreign companies that can really use rare earths to extract rare elements and use them in their own alloy materials.

They buy rare earth products, manufacture finished alloy materials, and sell them domestically to make a lot of money.

This is the technology gap.

Therefore, even if the melting point of K03A is raised to over [-] degrees, and they are doing research on adding rhenium elements, they just want to continue to increase the melting point by [-] degrees, and catch up with the international advanced level, which is quite remarkable.

Now that the melting point of the finished product has increased to over 1600 degrees, it is something that they dare not even think about. They all think that it is already possible, and they are already the second in the world. Do they still want to strive for the number one in the world?

"in addition……"

"What's the use of striving for the number one in the world?" Not only Li Rongmao, Zhang Hongtao, but even Wang Zhifang thought so, "Even if you make the most advanced nickel alloy with the highest melting point, what's the use?"

"It's not necessary!"

"The domestically produced engine is simply useless!" They just thought in their hearts and didn't say it out.

Zhao Yi seemed to be able to read everyone's minds, and he said seriously, "I know everyone is satisfied with the current results, but I am like this, no matter whether it is useful or not, as long as I do it, I must do my best!"

"Now the melting point of the material we have produced exceeds [-] degrees. Indeed, the performance is sufficient for use."

"However, I don't want to see that one day, when there is a demand for domestic manufacturing, we will find that the properties of the materials we are currently researching cannot keep up, and our materials will be replaced by new materials."

"Group Leader He, do you have any experience?"

As Zhao Yi said, he turned his head and saw He Guilin.

He Guilin had the same thought as others, but after hearing what Zhao Yi said, he immediately nodded empathetically, "That's right, more than ten years ago, we all thought that the performance of K03A was enough, but later Kunlun and Wangwu engines , They all think that our performance is not enough, and we just use K03A because we have no choice."

"Our entire R&D team knows that it is only a matter of time before K03A is replaced!"

"That feeling...how should I put it?"

"Anyway, I think our whole group is useless." He Guilin looked at the others and said, "I support Academician Zhao, and the research will continue. Since we can work hard and try to improve the performance of materials, why not Woolen cloth?"

After He Guilin finished speaking, everyone else nodded.

indeed.

There is no rush to announce the results. It is indeed very powerful to develop the world's second material, but who doesn't want to be the world's first?It's like an international Olympic game, who cares about the silver medalist?

……

R & D, continue.

The next step is to demonstrate, and then invest in the third experiment. The third experiment took a week as a whole. The speed can be said to be quite fast, and the results are also very good.

The performance of the finished product has been improved again, the melting point has reached 1640 degrees, and the strength has not changed.

Zhao Yi decided to continue the demonstration experiment.

The fourth experiment took six days, including the previous demonstration and the experimental part, and the performance of the final product was improved again --

The melting point is 1650 degrees!

The fifth experiment took only five days because only two parts of the design were modified. Unfortunately, the finished product obtained in the final experiment did not improve on the basis of the fourth experiment.

"The melting point is still 1650 degrees!"

"It's similar to the finished product last time. When I tested it, it felt like the same thing, even the color was exactly the same."

"What about the strength?"

"It's the same, at least the difference cannot be distinguished, even if it is the same product produced in different batches, there will be such differences."

"..."

The people in the R&D team are all sighing, maybe because they are used to the improvement. This is the case in the previous few experiments, and each time the melting point of the finished product will continue to increase.

This time there was no improvement at all, which made them feel disappointed.

Zhao Yi didn't care at all, "This is also normal, it's impossible to improve every time."

His words woke up the others.

They found that they were fascinated by doing research with Zhao Yi. When they were doing experiments before, not to mention improving the finished product every time, even if it was ten experiments, if the performance of the finished product was improved once or twice, it could be called research. Very efficient.

"But what's next?"

Wang Zhifang expressed the doubts of others, and everyone looked at Zhao Yi again, "Academician Zhao, do you have any plans?"

"Have."

Zhao Yi nodded, "After this experiment, we can confirm that Professor Shen's design has come to an end."

This is the conclusion.

Everyone else nodded.

They conducted several experiments in a row, and it can be said that they have excavated everything that can be excavated. Shen Binghe's design has been researched to the "international top", so there is no need to continue.

Zhao Yidao, "So we are going to start a new experiment. Didn't we have several proofs before? Li Rongmao, Zhang Hongtao..."

He called the names directly.

"correct."

Zhao Yi suddenly said, "This time we will find the most rigorous design, Academician Wang, I remember you were going to explain your design last time, now, is it okay?"

Wang Zhifang was stunned.

He thought of the entry-level design that was 'full of loopholes' in his backpack, and immediately waved his hand and said, "It's no coincidence, I didn't bring it today. Why don't we use Hong Tao or Rong Mao's design."

His tone was sure.

At this time, Zhang Hongtao stood up suddenly and said, "Mr. Wang, I know that you want to give us young people opportunities, but now you are doing research, very important research, and everything should be centered on research."

"When I came in the morning, I saw that you put the design in the bag." He said, went directly to the chair, took the bag and rummaged through it, and then said loudly, "I found it! Academician Wang, I said you must bring Already!"

He put the design in front of Wang Zhifang, "Academician Zhao said to find a rigorous design, so you can explain it. I believe that no one here can be more rigorous than your design!"

"..."

Chapter 438 Staged results!

"Zhang Hongtao, that dead boy!"

"I still talk about design, and I said I will give you a chance... This is different from the plan!"

Wang Zhifang sat awkwardly on the seat, looked down at the design, and didn't know how to speak for a while. His original plan was that the next time Zhao Yi asked for the argument of "low design level", he would openly fight against it, and then Take out this poor design in a fit of anger.

At that time, Zhao Yi may have adopted it.

The current situation is different from what he imagined. What Zhao Yi asked for was a rigorous design of argumentation, not a "low-level design" argument. As a result, Zhang Hongtao helped find this low-level argumentation?

"This... how to do?"

"It's impossible to say directly that I deliberately did such a low-level certification for the sake of adopting the design?"

Wang Zhifang gritted his teeth, and stared at Zhang Hongtao angrily.

Zhang Hongtao was a bit baffled. He thought it was Wang Zhifang who insisted on giving opportunities to young people, and hoped that his or Li Rongmao's designs would be interviewed and used in experiments. He was very moved and immediately said, "Mr. Wang, don't give us a chance."

"Now it's research, and everything should be based on research. Your design is more rigorous, and we all believe in you."

His words were sincere.

Li Rongmao followed suit, "You're right, research is the most important thing. For us, we can learn a lot by participating in this kind of project."

Wang Zhifang didn't know what to say for a while, he was stunned for a long time, took a deep breath, and explained in an awkward tone, "Actually, this design was made in my free time, it didn't take long at all, I just thought It should be used as a reference for my main design by reverse thinking."

"I still have a design..."

"Balabala~~~"

Wang Zhifang said a lot in a row, meaning that he made two designs. This design was very bad, but others still thought he was being polite and self-effacing, so he immediately took up the conversation and said, "Mr. Knowing you, even the casually designed designs are rigorous."

"You have very extensive experience, especially in design arguments."

"When you say that, we look forward to it even more."

"..."

Wang Zhifang had the urge to vomit blood. He simply scratched his head and started talking, but he only explained the design plan, that is, the process of the experiment. He didn't give a detailed explanation of the steps, and he didn't seem to expect others to understand.

After listening to a few words, Zhang Hongtao knew that what Wang Zhifang was talking about was not the design they discussed together. On the contrary, he looked forward to it even more. He listened carefully, and then found that there were many problems in the design. It seemed that every step was worth asking in detail. ?

"its not right……"

Zhang Hongtao thought to himself, "This design is worse than Shen Binghe's. Does Mr. Wang have any new ideas?"

Li Rongmao also heard it. He didn't know how to make an evaluation, thinking, "Could it be that because of Shen Binghe's design, the performance of the finished product has improved, and Academician Wang made a more 'surprising' one?"

Shen Binghe also listened very seriously, he thought suspiciously, "It seems that there is none, how much better than me?"

The three of them had their own thoughts and did not speak.

He Guilin didn't think about it so much. He found a free moment and asked directly in doubt, "Academician Wang, I heard several places just now, and the design seems a bit imprecise?"

"Cough cough~~~"

Wang Zhifang coughed several times in a row, quickly took a sip from the water glass, and then said, "So I said, this is a reverse design..."
