Rule department scholar

Looking at the car going away, He Guilin stood there in a daze for a long time. He kept thinking about Zhao Yi's words and Zhang Hongtao's special reminder.

"Academician Zhao visited for two days and didn't say a few words. Why did he suddenly come up with a suggestion?"

"When I said I wanted advice, it was just a polite way!"

"I really have a suggestion, continue to heat while mixing, and then directly perform deoxidation treatment..."

He Guilin carefully figured it out, and then thought of Zhang Hongtao's reminder, "Will you lose money if you try? But try...you still have to apply!"

What Zhao Yi said sounds simple, but in fact it is very troublesome to operate. The metal liquid is mixed with a jump mixer. As it is said, the liquid is poured back and forth, but you must know that it is a thousand-degree metal. Liquid, it is not easy to continue heating at such a high temperature.

After the metal liquid is mixed, skip the intermediate steps and directly carry out deoxidation treatment, which involves the furnace and other equipment in the manufacturing process, and the equipment needs to be adjusted and modified.

These are not up to the R&D team to decide.

Similar internal and external adjustments of equipment must be reported to the higher authorities to make a decision. During the adjustment process, the equipment must be stopped. The R&D team alone can't do it, let alone demonstrations. Knowing why, certainly cannot make an argument.

He Guilin thought again, "But what Zhang Hongtao said is also reasonable, you won't lose money if you try, and it's Academician Zhao's suggestion..."

Although He Guilin doesn't think that Zhao Yi has any research on alloy materials, he still needs to take suggestions, because Zhao Yi has created many miracles, and maybe the other party gave him advice because he found inspiration from other fields.

Still the same sentence, "Try it, you won't suffer!"

"Anyway, it's Academician Zhao's suggestion!" He Guilin suddenly figured it out. The thing is that Zhao Yi came to visit and gave suggestions on the manufacturing process. He just needs to make a report normally, adding his own "can try" idea, whether to "try" Just let the higher authorities make the decision, and it will definitely pass without any accidents.

Even if it is the suggestion of alloy material experts such as Zhang Hongtao and Wang Zhixin, the above will definitely consider it seriously, and will find many people to do the argument together, because the cost of "trying" is not low.

Zhao Yi is different. His cross-disciplinary suggestions will also be valued by his superiors.

the reason is simple--

His name is Zhao Yi!

……

the other side.

Zhao Yi, Zhang Hongtao and others sat in the car going to the capital. They had to stay in the car for ten hours, and they would definitely be very tired all the way.

Everyone else rested with their eyes closed, and Wang Zhixin couldn't calm down. He was always thinking about the problems Zhao Yi said, but he couldn't understand them, but he didn't want to speak, because he didn't agree with research on nickel-iron alloys. , I still feel that 'single crystal nickel alloy' is more promising.

The general direction is set by Zhao Yi, and the main researcher is also Zhao Yi. He is a veteran of alloy materials, and it is impossible to change the general direction.

Wang Zhixin knew that if he raised a small opinion, there would be no problem, and he could still show his knowledge, but questioning the general direction of research, no matter whether it was right or wrong, would definitely cause disagreements with Zhao Yi, and there is no doubt that the research and development team With Zhao Yi as the core, even half of his student, Zhang Hongtao, is more inclined to Zhao Yi.

This is the helpless place.

Wang Zhixin thought about a lot of things, but he had been doing research on alloy materials all his life, and he still wanted to understand things in the professional field, so he just gritted his teeth and said, "Academician Zhao? Academician Zhao? Are you asleep?"

"what happened?"

Zhao Yi opened his eyes and looked over.

Wang Zhixin said directly, "That's right. I've been thinking about it for a long time and I can't figure it out. Why did you make that suggestion? There shouldn't be any problem with the jump mixer, and I don't understand directly after mixing."

Zhao Yi scratched his head vigorously, and said, "I just think that the performance of the material produced that way is better."

Wang Zhixin's mouth was half-opened, but he didn't respond for a long time.

This……

Doesn't saying it mean not saying it?

He simply skipped the topic and came to the biggest question in his heart, "I heard from Hong Tao that you decided to do research on nickel-iron alloys and gave up on single-crystal nickel. I can't figure it out either. Why?"

Wang Zhixin was thinking in his heart, maybe Zhao Yi would reply, "I think nickel-iron alloy is more promising?"

This time he guessed wrong.

Zhao Yi's decision to do research on nickel-iron alloys was really deliberate. It was not just the reason he told Zhang Hongtao. He became much more serious and explained, "Our research and development goal is to make turbine blades. At present, we are not interested in turbine blade materials. needs, that is, to catch up with the international advanced level."

"Correct."

Wang Zhixin nodded.

Zhang Hongtao and Shen Binghe also opened their eyes and looked towards Zhao Yi, wanting to hear what he would say.

Zhao Yi continued, "For the most advanced fighter jets in the world, the temperature before the vortex of the engine is about 2000 degrees Celsius (1726.85 degrees Celsius), and the thrust can reach more than twelve tons."

"We want to make an advanced engine, and the demand is similar, and the final product will reach the standard of 2000 car."

"I think this standard can be achieved by improving the manufacturing technology of nickel-iron alloys. Single crystal technology is indeed very advanced, and the prospect of single crystal nickel is very broad. I also believe that, but we don't have such a high demand."

"Maybe in 30 or 40 years, when the sixth-generation, seventh-generation, and space-class fighters need more advanced engines, these advanced manufacturing technologies must be used, but now, they are not needed."

Zhao Yi finished speaking seriously.

Wang Zhixin, Zhang Hongtao, and Shen Binghe suddenly looked at it, and they were all so surprised that they didn't know what expressions to make.

"The demand is only 2000?"

"Isn't 2000 Kelvin too high? Ordinary metals have a melting point of only about [-] Kelvin! Alloys are more resistant to high temperatures, but in theory, alloys will only have a melting point about [-] Kelvin higher than the original metal."

"2000 is the upper limit!"

"Nickel-iron alloy can meet the requirements? Can't single crystal technology be used?"

If someone else said that, Wang Zhixin wanted to slap him, but he couldn't say anything to Zhao Yi, so he could only keep his doubts in his heart. At the same time, he also had an idea.

Zhao Yi gave advice to He Guilin. If He Guilin did what he said and really improved the performance of the final product, it would prove that Zhao Yi was not talking nonsense.

otherwise……

This project really has no future.

Anyway, it is simply impossible to expect him to improve and develop based on the domestic engine turbine blade material K03A.

……

Yanhua University.

After Zhao Yi and Shen Binghe returned from their visit, they started to build a metal material laboratory. The laboratory does not need to build a new house, because there are offices and conference rooms. It only needs to add a covered operating room. The site is large and empty. OK.

It is enough to draw a space next to the operation room of the power engineering laboratory. Zhao Yi took a look at it and decided to build a large-scale workshop next to it. They are only going to make the laboratory run and have some basic equipment. That's it. For demanding operations such as high-temperature furnaces, you can let the cooperative metal composite materials laboratory do it.

Yanhua University also supports the establishment of the metal materials laboratory. The school and departments not only directly approved the office and operation room, but also allocated a special fund of 100 million for expenses.

Some people who know it find it funny.

Mainly the name.

Metal Materials Lab?Isn't that the name of Shuanghang's alloy materials laboratory?

The word compound is missing...

Several professors and teachers from the School of Power Engineering and Mechanical Engineering, as well as the leaders of the departments, came to persuade Zhao Yi to change his name, but Zhao Yi was very specific about his name.

"Call this!"

"When I applied for the project, I used this. What's the name?"

"It's better not to repeat it anyway!"

The people who came here were all talking. They didn't know the details, but they knew that the reason for approving the project must be Zhao Yi, and it had nothing to do with the laboratory.

Even if Zhao Yi does not apply in the name of the laboratory, the project has a high probability of being approved.

Many people also envied Shen Binghe.

Shen Binghe is just an associate professor who has just signed a contract, and his professional title is only higher than that of ordinary lecturers. However, because the major of materials is newly established, he still has the highest professional title, and suddenly he has a laboratory with an investment of tens of millions. The pinnacle of work environment.

Amid the envy of others, Shen Binghe felt a lot of pressure. He didn't need to participate in the research for the time being, but the laboratory must be built, purchase and installation equipment, coordinate site issues, apply for various qualification certificates, etc., a lot He has to do everything alone.

Shen Binghe couldn't finish his daily work, he just felt very stressed, so he went to find Zhao Yi helplessly.

Zhao Yi was a little puzzled when he heard this, so he asked, "Why don't you hire someone? Only one person is busy? There are so many things, how can you be busy? And even if you are busy, the progress will be delayed."

"Isn't this thinking about saving money?" Shen Binghe explained with a wry smile, "You should also think more about buying equipment. For example, some equipment worth about [-] yuan can save tens of thousands of yuan by comparison."

"Money is not important, progress is important!"

Zhao Yi said very seriously, "It's best to get things done in the laboratory within a week, and it doesn't matter if you spend more money. The same is true for other things. What I need is speed, not saving money."

"Ah? So anxious?" Shen Binghe was a little surprised.

He felt that he was thinking about the project, building a laboratory would save some money, and he would be able to have more money for the project, and spending a little more time was nothing compared to it.

Zhao Yi shook his head and said in a very stern tone, "You have to keep up with the progress, you know? We are cooperating with Zhang Hongtao, but we can't do everything with them, otherwise it's not cooperation. We must be able to complete some basic experiments. Work, that's the most important thing."

"but……"

Shen Binghe struggled for a while before saying, "This project will take a long time, no matter what, it will take one or two years—"

"Who told you that?"

Zhao Yi frowned and said, "One or two years, I can't wait to start research now. Who can afford to wait for such a long time? The laboratory should be completed as soon as possible. Talk to Zhang Hongtao and start right away. I have already figured out what to do. Now, time is the most important thing, don't care about the money or not, as long as it doesn't involve large equipment or other things that can't be solved, the sooner the better, OK?"

Shen Binghe nodded vigorously, "OK!"

Zhao Yi and Shen Binghe spoke harshly, but he really couldn't see it and was a little anxious.

The visit to the 307 steel factory was very rewarding. He knew the manufacturing process of K03A nickel-iron alloy and learned a lot. , There are many problems that I have noticed, most of them are small problems, and it takes a long time to tell them. If there is a big problem, I will remind He Guilin directly.

These little problems are also big rewards.

After correcting all the problems, the K03A nickel-iron alloy manufacturing process becomes perfect, and the performance will definitely be improved to a certain extent, but because the corrections are all minor problems, the performance will not be qualitatively improved.

Zhao Yi's goal is not only to improve the manufacturing process, otherwise he would not need to apply for an additional project, and just go to the 307 steel factory for a turn.

The results of materials science are not important to him.

Now that the project has been applied for and a research and development fund of 2000 million has been obtained, it is necessary to produce alloy materials that exceed international standards.

If other people know that Zhao Yi's goal is to surpass the international level, they will definitely think he is crazy. How can the top international level be surpassed if he wants to, but Zhao Yi is quite confident, especially when he visited the 307 steel factory Finally, he obtained a lot of "realistic conditions" and understood the whole process of production and manufacturing. He knew that as long as the 307 steel factory perfected the manufacturing method, it would be enough to improve the performance of K03A.

This improvement is difficult to catch up with the top international level, but with the previous foundation and further improvement, the gap will not be so big.

After that it improved.

The research and development of alloy materials is too complicated. No matter the manufacturing method or the ratio of elements, there are countless combinations. There is no so-called "perfect formula" or "perfect method".

Zhao Yi doesn't need a perfect method either.

Just like what Wang Zhifang said, he doesn't need to produce very high-end alloy materials, just to catch up with the current international level, as long as he walks a correct path.

What is the right path?

Add rare elements --

铼！

The K03A turbine blade used by the Kunlun engine does not contain rhenium. It is known that adding rhenium is a good way, but how to add it and what kind of ratio have not been studied yet.

Rhenium is a high temperature resistant element with a melting point as high as 3180 degrees Celsius.

The purpose of adding rhenium to the alloy is to increase the melting point, but because pure rhenium is soft, too much rhenium added will affect the strength of the alloy, and the method and amount of addition are both problems.

Therefore, the main direction of research and development is to study the ratio and method of adding rhenium elements on the basis of perfecting K307A in the 03 steel plant.

Zhao Yi believes that the performance of the perfected K03A is already very good, and if the ratio and method of adding rhenium are studied, the performance of the final alloy will surely exceed the international advanced level. The process of research and development is to use various methods, various Matching to verify.

Every experimental verification can bring some conditions, and it will also help him better understand the situation after the addition.

After several experiments, it is almost possible to try out the ratio and method to increase the melting point efficiently and maintain or increase the strength of the alloy.

This is the development process.

……

Zhao Yi couldn't wait to start doing research. He wrote a report on perfect manufacturing, submitted it directly to the superior, and sent it to the 307 steel factory.

The R&D team of the 307 steel factory received the report, and they were all a little puzzled, "Academician Zhao came to visit and found so many problems in the manufacturing process? Is it okay to do what he said?"

He Guilin gave the answer, "Academician Zhao said that there were many small problems before he left, but he didn't expect to report directly, but let's verify the big problems he said first, and it's only been two days."

"Correct."

"Let's see the result."

The 307 steel factory adopted He Guilin's suggestion about Zhao Yi's problem, and quickly organized the transformation of the ultra-high temperature furnace and the jump mixer, so that when ferrosilicon and ferronickel are mixed, they can be kept in a heated state, and they can be directly mixed after mixing. Deoxidation treatment.

After completing the modification work, they went through a process to manufacture the new K03A.

On the afternoon of the second day after the R&D department of the steel mill received Zhao Yi’s report, the new K03A was manufactured. He Guilin led the R&D team to test the new K03A impatiently, and immediately came to an astonishing conclusion——

The melting point of the newly manufactured K03A is nearly 100 degrees Celsius higher than the original one!

Chapter 428 It's too early to get excited!
