If one distinguishes the direction of single crystal nickel from the direction of nickel-iron alloy, it can be said that single crystal nickel represents the latest alloy technology and research direction, while nickel-iron alloy belongs to the "traditional" technology.

Tradition seems to be eliminated.

This time Zhao Yi is in the 'traditional' camp, not because he is not optimistic about the direction of single crystal nickel, but because...

trouble!

It is too troublesome to apply for the research and development of single crystal nickel, and it is too troublesome to do the research and development of single crystal nickel. The latest technology also represents complexity. The process of 'single crystal' technology requires very high-end equipment, not to mention, starting from DD5 for research and development , but also to deal with the Metal Research Institute of the Academy of Sciences, and continue to do research and development with their achievements. Whose achievement is it after success?

After he thought about it carefully, it is completely enough to improve the nickel-iron alloy technology and the performance of the final finished alloy according to the existing needs, and does not require 'too superb' technology.

This is also the simplest and easiest direction.

After Zhao Yi and Zhang Hongtao made an agreement, they quickly expanded the names of the personnel involved in the research and development. Shen Binghe was added here by Zhao Yi. Added the name of Wang Zhifang.

In this way, there are four people participating in the research, namely Zhao Yi, Shen Binghe, Zhang Hongtao and Er Wang Zhifang.

They are the 'expert group' who visited the 307 steel plant.

After the project was approved, Zhao Yi applied to go to the 307 steel factory to visit the manufacturing process of nickel-iron alloy turbine blades. He received the news of his consent and reported the list of participants.

Personnel approval is very fast, and the timing still depends on the situation at the 307 steel factory.

……

307 Steel Plant.

Like other factories with a code name, the 307 steel factory also has a purely military background, and is a factory specializing in the production of alloy materials for the military.

The 307 steel factory has very complete production and manufacturing equipment, and has a research and development team belonging to the steel factory. It will participate in many national defense and military-industrial projects, including military weapons such as fighter planes, submarines, and tanks. The production process has 307 steel factory shadow.

Although the 307 steel factory is state-owned and military-owned, the research and development department of the steel factory is a bit embarrassing, especially the research and development team of some high-tech materials, which is so embarrassing that there is no sense of existence.

The research and development group of aerospace materials is like this.

Decades ago, the technology of the steel and products produced by 307 Steel Factory came from the internal R&D group, which was equivalent to doing R&D and production by ourselves. To meet the demand for materials in the aerospace field, steel mills had to use the results of outside scientific institutions.

This makes the existence of the aerospace material research and development group very awkward.

If the production of materials in the aviation field uses the results and directions of research and development by external institutions, they will become meaningless. However, it is a fact that the research and development capabilities cannot keep up. They have the best scientific research conditions, but they do not have the corresponding ability to attract talents. ability.

He Guilin, the current leader of the aviation material research and development team, is always worried about this matter. He is worried that one day, the steel mill will cancel the aviation material research and development team, but the problem he faces is that their aviation material team has been working for several years. Time, no material R&D breakthrough has been made.

Talent is the most important thing.

He Guilin very much hopes that more alloy material experts will join the aviation material research and development team of the steel plant, but it is a pity that most of the truly capable talents will choose to work in universities, academies of sciences, or scientific research institutions of enterprises , and in the absence of talents, it will be even more difficult for his aerospace material research and development team to produce any results.

"Ah~~"

Sitting on a chair, He Guilin read several reports on the failure of research and development experiments in a row. He was filled with helplessness, and he could only let out a long sigh.

"report!"

There was a shout from the door.

"Enter!"

He Guilin yelled softly, and a staff member came in and handed over a document, "It's the document above, for you to sign."

"Let me see."

He Guilin glanced at the documents and knew that there was an 'expert group' to visit the manufacturing process of turbine blade materials.

He couldn't help the corners of his mouth twitching.

The material of the turbine blades is nickel-iron alloy, and outside institutions are developing single-crystal nickel alloys. Single-crystal nickel alloys are considered to be the cutting-edge direction. This is where the embarrassment lies. His aviation material research and development team does not understand single-crystal technology. They are also doing research and development in the direction of single crystal nickel, but they have only made the beginning, and they don't know how to continue.

"It is estimated to be a single-crystal nickel alloy again. Let's take a look at the manufacturing process of nickel-iron alloy and give a reference to the direction of single-crystal nickel."

"If things go on like this, the aviation material research and development team will be dispensable, and 307 won't even have any technology of its own, and it will soon become a pure factory."

"Ah~"

He Guilin sighed again, but still signed the document.

……

Institute of Metal Research, Academy of Sciences.

The Capital Research Institute of Aeronautical Materials was the first to study single-crystal nickel alloys in China, and the Institute of Metal Research of the Academy of Sciences relied on its strong talent reserve and scientific research capabilities to develop DD5 from behind, and it is constantly improving to enhance the performance of the alloy.

The leader of this research is academician Peng Engui, who is the leading alloy material expert in China and has led the research and development of more than a dozen alloy materials that have caught up with the world level.

On the materials of turbine blades, Peng Engui undoubtedly has the right to speak, and the news in the industry cannot escape his ears.

soon.

Peng Engui and the R&D team he led knew that there was the third R&D project for turbine blade materials in China, and they also knew that Zhao Yi and Zhang Hongtao jointly applied for it.

It wasn't a big deal at first, at most there was competition in the speed of research and development, but he also heard that Zhao Yi's application report stated the direction of 'nickel-iron alloy', so it became very interesting.

The two research and development directions are naturally not competitors.

Peng Engui entered the laboratory and a few people in the research group, and it was a bit funny to talk about it, "Zhao Yi, research alloy materials? Did he switch from theory to application? Even if he switched to application, it should be applied mathematics. What are you doing?" Alloy material research."

He shook his head as he spoke, and said in a teaching manner, "What is the most important thing in our business? Experience!"

"Experience is the most important thing!"

"Mathematics and physics are all based on theory. Only with the support of theory can we develop applied mathematics and applied physics. Alloy materials are different. If you talk about theory, can you deduce the manufacturing method of alloy? No!"

"This research is a process of continuous trial and error and continuous improvement. Knowledge is in the process of experimentation and research, so experience is the most important."

Several researchers also nodded, "Academician Peng is right! It makes sense!"

"Our research is just constant trial and error. Maybe that step, if you increase the temperature and time, it will be done!"

"Academician Peng speaks from experience!"

Peng Engui was flattered a few times, and felt a little embarrassed, so he continued, "Zhao Yi, let's not talk about it, a genius, Zhang Hongtao has some skills, he is really lucky, he can imitate the outer skin of a satellite at a young age." , It is said that the research on the deck of the aircraft carrier has also yielded results."

"Shuanghang's alloy laboratory is also high-level. Academician Wang Zhifang's level of ability is worthy of recognition. It is said that he has also joined the research and development team."

"but……"

As he spoke, there was a change in his voice, "They chose the wrong direction. Nickel-iron alloy? There is no prospect! There has been no progress for many years. It is impossible for them to produce results once they do it."

"Are you right?"

……

A week later.

Zhao Yi, Zhang Hongtao, Wang Zhifang and Shen Binghe visited the No. 307 steel factory together. When they arrived at the airport, they were greeted by the staff of the steel factory. After entering the factory, they met He Guilin.

He Guilin is the leader of the aviation research and development team, and the relevant "expert group" must visit him to entertain him.

The year before last, a group of experts from the Academy of Sciences also came to visit. He Guilin once entertained, but this time there were fewer people.

"Zhao Yi, Academician Zhao?"

He Guilin opened his mouth wide in surprise, only to realize that he didn't read the name list carefully, and just signed and waited.

But seeing Zhao Yi was just a surprise. He still performed his duties as a "tour guide" normally, explaining to them the manufacturing process of nickel-iron alloy, the material of the turbine blades, and taking them on a tour of the large workshops in operation, as well as the high-temperature melting furnace and the molding room. And other equipment, also find an opportunity to inquire about the research and development of turbine blades by the 'expert group'.

It's nothing to keep secret.

"We are just doing research on improving nickel-iron alloys, and we have just started, so we just came here for a visit." Wang Zhifang said it directly.

He Guilin asked in surprise, "Isn't it single crystal nickel?"

Wang Zhifang looked at Zhao Yi with depression, and said weakly, "Isn't there other institutions that are making single crystal nickel?"

He convinced himself with this reason before deciding to join the research and development project.

Of course, the most important thing is that he is very interested in the research of turbine blades. Even if he can't produce any results, the opportunity should not be missed.

He Guilin noticed Wang Zhifang's eyes and knew that the "expert group" was led by Zhao Yi, so he was not surprised, because Zhao Yi's reputation was too great and his influence was too great. The research team is probably also a core figure. It is not a strange thing for Zhao Yi to cross fields.

To his surprise, Zhao Yi decided to study 'improved nickel-iron alloy' instead of single crystal nickel.

"Isn't this a bit unprofessional?"

"Improve the nickel-iron alloy? If it could be improved, we would have already achieved results!"

He Guilin was a little confused.

The visit to the work process lasted for two days.

Among them, the actual visit is only four to five hours, and the rest of the time is waiting for the manufacturing process. For example, if there is a high-temperature smelting furnace, it will take more than an hour to activate the "ultra-high temperature state", because the demand is not so high, and it will only be used once a week. It is activated once, and the rest of the time is just to maintain the high temperature. It is impossible for the expert group to visit and activate the 'ultra-high temperature state', but to maintain the normal production state, and they have to wait.

Among the four members of the 'expert group', both Zhao Yi and Shen Binghe visited the steel factory for the first time.

Zhang Hongtao has been to steel mills several times, but he has very little experience and doesn't know much about real production.

Wang Zhifang is very experienced. There are no unexpected parts in the manufacturing process of nickel-iron alloys. It is just a careful look at some details and specific questions. Because of this, he just looks at the whole process.

Both Zhao Yi and Shen Binghe had no experience at all, and even Shen Binghe was considered a 'pure layman', most of the time he just listened to He Guilin's explanations and looked down at the materials in his hand.

Zhang Hongtao communicated with He Guilin the most. He frequently asked questions about R&D and manufacturing, and many questions always got to the point. good."

Capable young researchers represent hope and possible future achievements.

He Guilin was very enthusiastic about Zhang Hongtao. At first, it was okay, but later he felt that Zhang Hongtao was like the 'leader', and the others were incidental foils, and he was the one talking during the visit.

Zhao Yi, Wang Zhifang, and Shen Binghe all watched silently from the sidelines. Wang Zhifang felt good about Zhang Hongtao's ability, but Zhao Yi and Shen Binghe didn't respond at all.

Zhao Yi did not care.

Shen Binghe walked at the end for a long time, without any thoughts at all, he almost held up a sign and said, "Shooting soy sauce, passing by..."

He is just an incidental person, and his participation in the projects is 'passive', so what's your opinion?

Two days later.

After inspecting the final cooled materials and visiting the R&D office building, the visit is almost over.

He Guilin exchanged pleasantries with Zhang Hongtao, and sent them out. He also had an evaluation in his heart. He felt that Zhang Hongtao was a very capable young man, and the future in the field of alloy materials was limitless.

Naturally, Wang Zhifang didn't need to say much.

The old academician didn't say much throughout the whole process, but he can be evaluated as an academician of the Academy of Engineering in the field of alloy research and development, and he is also a pillar of materials science at the University of Aeronautics and Astronautics. There is no need to question his ability.

Zhao Yi is an outsider.

Shen Binghe was like an assistant, he seemed to understand some alloy issues, and he didn't seem to understand anything.

"It is said that Academician Zhao decided to study and improve nickel-iron alloys, and I don't know why..."

"A layman directs an expert?" He Guilin couldn't figure it out, so he didn't think too much about it, since his work was over anyway.

A group of people walked to the main entrance.

He Guilin gave a symbolic greeting, "Thank you for visiting! You are all experts in the field of alloy materials. You have visited our production and manufacturing process. If you have any valuable opinions, you would like to mention them!"

Wang Zhixin nodded with a smile, waved his hand and said, "What experts are not experts, your technology is already perfect."

Zhang Hongtao said, "We are here to observe and study."

"Speaking of which, I really have a suggestion." Zhao Yi said suddenly.

Others looked over immediately.

Zhao Yi said, "Group Leader He, I watched the whole process and found that there are many problems!"

He Guilin smiled awkwardly.

Zhao Yi continued, "However, it's just a small problem regardless of the ratio. There is one thing that I think can be improved, that is, when mixing ferrosilicon and ferronickel, you use a jump mixer to pour it. Let’s not talk about this technology, but I think at this time, in order to prevent the temperature from dropping, we should use continuous heating to keep the process temperature constant.”

"After mixing, continue to maintain high temperature, and perform deoxidation treatment directly and quickly, without intermediate steps."

He finished and added, "That's the suggestion. You can try it. I think it should improve the performance of the final product."

He Guilin was a little taken aback.

He didn't expect Zhao Yizhen to say a set of things, or the very detailed things in the manufacturing process, and he didn't know how to react for a while.

Zhang Hongtao's reaction was quick, and he immediately followed up, "Group Leader He, Academician Zhao is the real expert, and his advice is really valuable, you must try it!"

He also specially warned, "Listen to me, try it and you won't suffer!"

"Okay, okay, sure, sure!"

He Guilin didn't know how to react, so he quickly nodded in agreement and sent several people to the car.
