The Literary Life of a Science Leader

Chapter 182 Materials Research Seminar (13)

The success of the original Z325 aluminum alloy series was actually a coincidence.

To be honest, Mu Jingchi didn't expect the results to come out so quickly.The results will definitely come out, but this is a matter of probability and luck. It may be the first time, or it may be the last.

The reason why it is said to be inevitable is that in the material research and development that time, Mu Jingchi used a lot of relevant knowledge in the future. These material scientific knowledge laid a very solid foundation for material research and development, making the breakthrough of new materials seem to go with the flow Naturally, it will follow suit.

"However, in the knowledge of the future, only dislocation theory is systematic, and many other knowledge are scattered in nature, which is really difficult to deal with!"

Participating in the nickel-based superalloy project, Mu Jingchi did not paddle or water papers, and now he no longer needs papers to prove himself.

But this is very important for his subsequent material path, so Mu Jingchi intends to seriously participate in it.

"Professors Gao and Xu should increase the proportion of research related to dislocation theory and application technology, but this is not a new type of nickel-based superalloy, it can only be regarded as an enhanced nickel-based alloy."

Mu Jingchi has a broad mind. He does not want to just make enhanced high-temperature alloys, but to develop innovative new materials that further transform the material's microstructure and organization.

"Material thermodynamics, molecular dynamics, atomic diffusion, solid phase transformation, solidification and crystallization, we still need to think of ways to find a way out of these future knowledge."

These aspects will also gain vigorous development in the future, and the research will become more in-depth and extensive.It's just that compared with the system of dislocation theory, these future knowledge are somewhat divergent, and it is difficult to build a mature system.

Furthermore, the knowledge that Mu Jingchi has acquired is all from future textbooks, and the knowledge in the textbooks are all theories shown, as for the application, they are not well known.

"Similar to the dislocation theory, we must first find a theoretical direction that is feasible in nickel-based high-temperature alloys. Then we seek solutions in application processes based on this theoretical direction. Only by combining material science with material engineering can we truly achieve new materials. research and development.”

With his own thoughts and ideas in mind, Mu Jingchi put them into action, started to take action seriously, and began to check the various materials piled up in this office.

To enter the military project of nickel-based superalloys, he naturally made serious preparations. Whether it was monographs or literature, he read a lot, and also studied a lot of current related frontier topics.

But after all, it is just a thesis, and there are only some directions, and there is not much detailed actual data. It can be used as a guide, but it is not enough as a future direction guide.

Therefore, the real and detailed data and various experimental plan designs in Yanshan Iron and Steel Research Institute are very useful to Mu Jingchi.

"What have you been doing these days, leaving early and returning late every day?"

Song Xiaoyi was lying on the sofa at home tired and paralyzed. After receiving the water handed by her mother, she gulped and drank it, and drank it all in one gulp.

"Comfortable!"

The temperature in Yanjing is getting higher and higher. Song Xiaoyi is running outside all day now, so she is naturally a little tired and hot.

"Where do I look for furniture and home appliances in various furniture and home appliance stores?"

Song Xiaoyi patted the sofa next to him and motioned for his mother to sit down too.

After seeing her mother sitting down, Song Xiaoyi also started talking to her mother, "Didn't you say you wanted me to move out with Mu Jingchi?"

"It was moved to a special national defense complex. Mu Jingchi chose a villa by the lake. He was very busy with things, so he entrusted me with the decoration of this villa."

"Aren't I just looking at furniture and home appliances outside these two days?"

Mother Song's eyes lit up when she heard this, "I live in a villa, isn't it big?"

Song Xiaoyi tilted her head and recalled the entire layout of the villa, "The building is not very big, it is considered small among all the villas, but the yard is very big."

"He said that the area was too big for the two of us to live in, so it looked deserted, so he didn't choose a villa with a large floor area."

Mother Song curled her lips, and pressed her finger on Song Xiaoyi's forehead, "You girl, don't tell us about such a big matter. Dad and I can help choose furniture and appliances together? There are also lamps, sofas, beds, desks, etc. Waiting for these things to be carefully selected, how can you do it well by yourself.”

"Don't, don't, don't."

Song Xiaoyi quickly waved his hand, "I've already done it. I have selected a few designers to participate in the decoration of the furniture and appliances you mentioned, as well as house lamps, sofas, beds, desks, etc. We don't need to do it ourselves."

"Why so fast? It's only been a few days, and you're worried that the fine decoration plan for the house has been completed?" Song's mother was still unwilling to give in, "Isn't it unreliable?"

"Don't worry, I sent the selected plan to Mu Jingchi via WeChat, and we all agreed."

After hearing that Mu Jingchi also nodded in agreement, Mother Song had no choice but to give up.

"Both of us like a simple and breezy style, so it looks more majestic." Song Xiaoyi and his mother said, "If you also participate, I can still bear your style, but I'm afraid Mu Jingchi won't like it. Now Times are different, aesthetics are different.”

Mother Song agrees with this.

"That's right, decorating your home is considered a prestige. Although your dad and I have read some books, we can't be regarded as educated people. It would be bad if we were self-defeating."

Without continuing to struggle with this issue, Mother Song asked happily again: "When will the decoration be finished? Let me go with your dad to have a look?"

"The villa itself has been renovated and does not require major changes, so it will not take a long time. It will be almost over in five days."

As Song Xiaoyi spoke, he stared at his mother with shyness in his eyes.

"Also, once the villa is decorated, Mu Jingchi's parents will come over and you can meet together."

Although she had already met Mu Jingchi's parents, her own parents hadn't. The meeting this time was almost the last step in getting the marriage certificate. If there was no problem, both parties could go to get the marriage certificate.

Therefore, when it comes to the whole thing, Song Xiaoyi is still very embarrassed.

"Okay!"

Song's mother slapped her thigh, "We used to only meet in this corridor and talk about common things, but now we are in-laws, so of course we will kiss each other."

this day.

The nickel-based superalloy project team of Yangang Research Institute was about to hold a meeting, and director Hao from the military also came over again.

Everyone receives different knowledge, thinks differently, has different personalities, and ultimately develops different scientific research directions.

This kind of research conference is to publish your own scientific research directions and ideas, and everyone can discuss the research direction together.As the saying goes, one person is short-term, two people are long-term, and three people are wise. Everyone has their own inappropriate considerations. After rounds of discussion and research, rounds of speculation and revision, the final research direction is at least reliable. of.

Mu Jingchi naturally also came to participate in this kind of seminar.

He also brought his own research direction, and Mu Jingchi didn't know whether it would be recognized by the people in the project team.After all, he has never participated in a high-temperature alloy project. It can only be said that the theoretical direction and ideas are somewhat original.

"Dr. Mu, you can help me take a closer look. If there are any shortcomings, please give me some advice."

People in the theoretical research room arrived one after another. When Mu Jingchi arrived, Hao Chen also arrived, so the two walked into the theoretical research room together. Director Hao greeted Mu Jingchi with a smile on the sidelines. Rather low.

"Director Hao, you are flattering me too much." Mu Jingchi smiled bitterly, "If you ask me to give you some advice on dislocations, I would naturally be obliged to give you some advice. But as for the subject of high-temperature alloys, I'm really a newcomer."

"Dr. Mu is too modest."

After entering the theoretical research room, Hao Chen and Mu Jingchi automatically walked to the last seat and sat down, "Although you have not carried out related high-temperature alloy projects, you have unique vision and talent, and you can see things that we can't see. Find problems wherever you go.”

"Just for this point, it is well-deserved to mention it."

"Since Director Hao has said so, I will naturally go all out."

This research seminar was different from the last seminar directed by Mu Jingchi. There were almost no researchers at the meeting this time, and all the attendees were big-name figures.

Because determining the theoretical direction is not what those researchers can do, but these big-name figures determine it.

Everyone knew Mu Jingchi's face, and after greeting each other, the seminar officially started.

The first person to play was Gao Mingsong, the leader and one of the persons in charge of the team. Gao Mingsong went straight to the core issues without any kind of official language about politics.

"The working temperature of nickel-based superalloys has reached 1100 degrees Celsius. In order to continue to improve the high-temperature resistance of nickel-based superalloys, Dr. Mu's dislocation theory has made a good start, which can optimize the microstructure of the alloy."

"But what I want to talk about today is a further direction. I still prefer to conduct research in heat treatment."

"My research direction..."

Cast superalloys still require heat treatment, including solution treatment, intermediate treatment and aging treatment.

Taking Udmet 500 alloy as an example, its heat treatment system is divided into four stages: solution treatment, 1175 ° C, 2 hours, air cooling; intermediate treatment, 1080 ° C, 4 hours, air cooling; primary aging treatment, 843 ° C, 24 hours, air cooling ; Secondary aging treatment, 760 ° C, 16 hours, air cooling.

In this way, the required organizational state and good overall performance can be obtained.

In this heat treatment stage, there are many steps and operations that need to be studied. What kind of treatment method is the best, what kind of temperature is the best, and the sequence of heat treatment steps. These involve a lot of research.

In order to change the microstructure of the material and achieve better material performance, each step must be studied in depth.

　Don't say anything, any reason is just an excuse, just say it honestly.
