The success of the original Z325 aluminum alloy series is actually inevitable by chance.

said that it was accidental, but Mu Jingchi didn't expect to produce results so quickly. The results will definitely come out, but it's a matter of probability and luck, maybe for the first time, maybe for the last time.

The reason why it is inevitable is that in that material research and development, Mu Jingchi used a lot of relevant knowledge in the future, and these material science knowledge laid a very solid foundation for material research and development, making the breakthrough of new materials seem natural and natural.

"However, in the future knowledge, only the dislocation theory is systematic, and many other knowledge is fragmented, which is really a bit difficult!"

Involved in the nickel-based superalloy project, Mu Jingchi did not have a paddling or water paper, and he no longer needed a paper to prove himself.

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

"The theory and application technology of dislocation should be increased by Professor Gao and Professor Xu in the research, but this is not a new type of nickel-based superalloy, only an enhanced nickel-based alloy. ”

Mu Jingchi's mind is still very broad, he does not want to just do superalloy reinforcement, but to do innovative research and development of new materials to further modify the microstructure and structure of materials.

"Material thermodynamics, molecular dynamics, atomic diffusion, solid phase transformation, solidification and crystallization, it is still necessary to find a way out of these future knowledge. ”

These aspects have also been vigorously developed in the future, and the research has become more and more in-depth and extensive. It's just that compared with the system of dislocation theory, these future knowledge are somewhat divergent and difficult to build into a mature system.

In addition, the knowledge obtained by Mu Jingchi is also from the future textbooks, and the knowledge in the textbooks is all the theories shown, and the application is unknown.

"As with the dislocation theory, it is necessary to find a feasible theoretical direction for nickel-based superalloys. Then, in this theoretical direction, we should seek solutions in the application process, and use material science with material engineering to truly achieve the research and development of new materials. ”

With his own thoughts and ideas in his heart, Mu Jingchi also put them into action, and began 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 relevant preparations carefully, whether it was a monograph or a literature, he read a lot, and also studied a lot of cutting-edge topics that are now related.

But after all, that's just a paper, some are just some directions, and there is not much detailed actual data, which can still be used as a guide, but it is not enough as a direction guide in the future.

Therefore, the real and detailed data in Yangang Research Institute and the design of various experimental schemes are very useful to Mu Jingchi.

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

Song Xiaoyi was tired and paralyzed on the sofa at home, took the water handed by his mother and began to drink it with a grunt, and drank it all in one gulp.

"Comfortable!"

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

"What about furniture and appliances in various furniture and appliance malls?"

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

After seeing her mother sit down, Song Xiaoyi also began to talk to her mother, "Didn't you say before that you wanted me to move away with Mu Jingchi?"

"It was moved to the national defense community, Mu Jingchi chose a villa by the lake, and he was very busy, so he handed over the decoration of this villa to me. ”

"Haven't I been outside looking at furniture and appliances for the past two days?"

Mother Song's eyes lit up when she heard this, "Living in a villa, is it big?"

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

"He said that only the two of us lived in it, and the area was too large and it seemed deserted, so he didn't choose a villa with a large construction area. ”

Mother Song pursed her lips and pressed a finger on Song Xiaoyi's forehead, "You girl, don't tell us about such a big thing, my father and I can help choose furniture and appliances together? ”

"Don't, don't, don't. ”

Song Xiaoyi hurriedly waved his hand, "I have done a good job, I have selected a few designers, and I will participate in the decoration of the furniture and household appliances you mentioned, as well as house lamps, sofas, beds, desks, etc., without us doing it ourselves." ”

"Why is it so fast? It's only been a few days, and you're afraid that the fine decoration plan of the house has been done?" Song's mother was still unwilling, "Will it be unreliable?"

"Don't worry, I sent all the plans I chose to Mu Jingchi on WeChat, and we all agreed. ”

As soon as she heard that Mu Jingchi also nodded in agreement, Song's mother had no choice but to give up.

"We both like to keep it simple and windy, so it looks a little more atmospheric. Song Xiaoyi said to her mother, "If you also participate, I can bear your style, but I'm afraid that Mu Jingchi won't like it, now the times are different, and the aesthetics are different." ”

Mother Song agreed.

"Also, the decoration of the house is also a face, although your father and I have read some books, but we are not cultural people, it will not be good if it is self-defeating. ”

Without continuing to dwell on this issue, Song's mother happily asked again: "When will the decoration be completed?"

"The villa itself has been renovated and doesn't need a major change, so it won't take long and will be almost there after five days. ”

Song Xiaoyi said as she spoke, staring at her mother, her eyes showing shyness.

"What's more, after the villa is decorated, Mu Jingchi's parents will also come over, and you will meet together when the time comes. ”

Although she has already met Mu Jingchi's parents, but her own parents have not, this meeting is almost the last process of getting a marriage certificate, if there is no problem, both parties can go to get a marriage certificate.

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

"Okay!"

Mother Song slapped her thigh, "We used to only meet in this aisle and say some common words, but now we have become in-laws, of course, it is kissing and kissing." ”

···

this day.

The Yangang Research Nickel-based Superalloy Project Team was about to hold a meeting, and Director Hao of the military also came over again.

Everyone receives different knowledge, different thinking ideas, different personalities, and ultimately creates different scientific research directions.

The purpose of this kind of research conference is to release their own scientific research directions and ideas, and everyone can discuss the direction of research together. As the saying goes, one person counts the short, two people count the long, and the three people plan properly, everyone has their own considerations of inappropriateness, after rounds of discussion and research, rounds of speculative revisions, the final research direction is at least reliable.

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

He also brought his own research direction, and Mu Jingchi didn't know if it could be recognized by the people in the project team. After all, he has never participated in the superalloy project, and can only say that he is a little ingenious in terms of theoretical direction and ideas.

"Dr. Mu, you can help take a good look, and if there are any shortcomings, please give me more advice. ”

The people in the theoretical research room all arrived one after another, and when Mu Jingchi arrived, it happened that Hao Chen also arrived, so the two walked into the theoretical research room together, and Director Hao greeted Mu Jingchi with a smile on the side, and his posture was very low.

"Director Hao, you are praising me too much. Mu Jingchi smiled a little wryly, "If it is a dislocation topic, if you ask me to mention it, I am naturally obliged, but I am really a newcomer to this superalloy topic." ”

"Dr. Mu is too modest. ”

After entering the theoretical research room, Hao Chen and Mu Jingchi automatically walked to the last chair and sat down, "Although you have not carried out relevant superalloy projects, you have a unique vision and talent, and you can find problems from places we can't see. ”

"That's the reason for that. ”

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

This research seminar was different from the last seminar under the guidance of Mu Jingchi, and there were almost no researchers attending the conference this time, and all of them were Dana-level figures.

Because determining the direction of the theory is not something that can be done by those researchers, but by these high-level figures.

Everyone knew the faces of Mu Jingchi, and after greeting each other, the seminar officially began.

The first to play was Gao Mingsong, one of the leaders and leaders of the team, and without all kinds of official words in politics, Gao Mingsong went directly to the core issues.

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

"But what I'm going to say today is to go further, and I'm still inclined to do research in heat treatment. ”

"My research direction... ”

Cast superalloys still need to be heat treated, 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, and secondary aging treatment, 760°C, 16 hours, air cooling.

In this way, the required state of organization and good overall performance are obtained.

In this heat treatment stage, there are many steps and operations to be studied, what kind of treatment method is the best, what kind of temperature is the best, and the steps of heat treatment are sequential, which involves a lot of research.

To achieve the change of the microstructure of the material to achieve better material properties, each step must be studied in depth.
