Chapter 68 Ultra-High Density Tungsten Alloy Materials
"That's good, congratulations, it's good to study when you go abroad, and foreign technology is very advanced. After the shock, Zhang Yi felt that since Xia Jingyan had this opportunity, it was not bad.
At this time, the domestic industrial technology can be said to be lagging behind Europe and the United States, after more than ten years of catching up, only to narrow the distance slightly, 98 years is still the stage of comprehensive learning.
Xia Jingyan smiled slightly: "Thank you, I just want to go abroad to see more, learn more, and gain some experience." ”
Zhang Yi said: "Did you look for me because of this?"
Xia Jingyan nodded and said: "Well, this is one of the reasons, and the other is that I am not familiar with Professor Rob's research topic, and I have been staying in the laboratory during this time, and I want to familiarize myself with the research content first, you know so much, I want to ask you for advice." ”
Professor Rob?
Zhang Yi felt funny in his heart, and he thought it was Professor Radish if he didn't know.
He wasn't familiar with Professor Turnip, Australia was so big, there were countless well-known professors, and Professor Rob wasn't engaged in mining research.
However, the scientific research of engineering has the same goal, he is engaged in mining and also understands materials, and environmental engineering may not be ignorant, after all, many principles are the same.
And Xia Jingyan is only a junior college student, and she won't be too demanding when she goes to Australia, can't he be a postdoctoral fellow to solve such a simple problem? Zhang Yi smiled and said: "Okay, if there is anything I don't understand, I can communicate with you, I dare not say that it must be right, but it is okay to give you a little advice." ”
Xia Jingyan was also very happy when she heard this, the topic she was now exposed to was an unfamiliar subject to the classmates around her, and few people understood it, and even if someone had heard of it, she didn't know as much as her, and no one could give her guidance.
This made her distressed for a while, at this time she suddenly remembered Zhang Yi, she also deeply remembered that she worked overtime to check the information and did not have an eyebrow tungsten molybdenum separation experiment, Zhang Yi solved it lightly, which made her can't help but go to the mining engineering to find Zhang Yi, hoping that Zhang Yi can give her some advice.
"You wait for me. Xia Jingyan turned around and ran into the laboratory, and when she came out again, she had a small notebook in her hand, and when she opened it, it was densely packed with many questions.
There are experimental phenomena, there are experimental principles, in short, she writes down the things she doesn't understand.
"Zhang Yi, do you know why these phenomena occur in these places?" Xia Jingyan timidly pointed to one of the places and asked, she was a little worried that the preparations were not done well, afraid that Zhang Yi would think that you didn't understand anything.
Zhang Yi took the notebook and looked at it, which detailed the name of the research topic, the introduction and the experimental process.
It turned out that Xia Jingyan was doing "research on the selective adsorption of heavy metals by high-sulfur activated carbon".
After the Great Industrial Revolution, the natural ecological environment of the West was greatly damaged, and since then, it has vigorously promoted the control of pollution and vigorously developed scientific research and technology for pollution control.
He doesn't know much about activated carbon, but heavy metals are his strength, and he knows all the forms of existence of heavy metals in aqueous solutions.
This somewhat ambiguous meeting finally turned into an academic exchange, and both of them were immersed in the subject, and before they knew it, an hour passed.
The students who were doing experiments in the laboratory were also surprised, they had never seen Xia Jingyan talk to a boy for so long, and they never pretended to be a boy Xia Jingyan, which made them curious about Zhang Yi's identity.
At the end of the conversation, the subject matter was almost over, Zhang Yi thought that it was not too early, and it was time to go to Professor Zhong's side to have a look, and left the environmental engineering laboratory after saying goodbye to Xia Jingyan.
When Zhang Yi left, it suddenly rained outside, and for some reason, his mood became a little melancholy.
Could it be that he was worried that Xia Jingyan would be very difficult to live abroad alone?
After shaking his head vigorously to stop thinking about these non-existent things, Zhang Yi went to Professor Zhong's laboratory by the way after leaving the laboratory of the environmental engineering major.
Unexpectedly, Professor Zhong was actually in the laboratory at this time, and after seeing him, he directly pulled him to the office.
As soon as he sat down, Professor Zhong said: "Zhang Yi, you were not there a few days ago, I went to report last week, Director Wu is very satisfied, and according to our progress, in another month, I think our technology can be put into production." ”
Zhang Yi nodded and said: "The experiment is quite smooth, the indicators are already very close to the requirements, or it won't be long before the project can apply for defense." ”
As if he suddenly thought of something, Professor Zhong frowned and said, "However, Director Wu seems to be a little anxious, urging us to hurry up, is there some problem in the follow-up scientific research." ”
Zhang Yi said with a smile: "Our progress is already similar to riding a rocket, how fast can it be." ”
Professor Zhong nodded and said, "That's right, you have to do experiments steadily, it's not okay to be aggressive, and you can get the best results by doing it systematically." ”
As if thinking that the tungsten and molybdenum separation progress was too fast, Professor Zhong immediately added: "Of course, knowing the method is another matter. ”
After having a good discussion with Professor Zhong about the content of the experiment, Zhang Yi processed all the recent experimental data in the studio and then went back to the dormitory.
The experiment was progressing well, and there was nothing to worry about.
......
It was when Zhang Yi and Professor Zhong were discussing the tungsten-molybdenum separation experiment.
Institute of Physics, Chinese Academy of Sciences, Jiangcheng.
In the conference room next to Director Wu's office, the conference room was full of smoke and miasma at this time, and eight people sat around a large round table, almost each holding a cigarette, constantly puffing.
Ahem, Director Wu seemed to suck a little hard, coughed twice, fanned the smoke ring in front of his nose with his hand, spat out from his mouth and said, "Lao Liu, tell me, is there any other way to do this experiment?"
Director Wu's old name is Liu Yuan, who is the director of the high-tech materials laboratory of the institute, and this experiment was carried out in the laboratory he was in charge of.
Hearing Director Wu call his name, Liu Yuan shook his head and said: "Director, we all know that tungsten alloy has the advantages of high strength, high hardness, good ductility and so on, but if you want to make its compressive strength reach 1,000MPa, the elongation does not exceed 10%, and it also needs to achieve ultra-high density, which is too difficult, this belongs to the category of powder metallurgy, and our technology does not meet the requirements at all." ”
At this time, the institute has begun to conduct research on ultra-high-density tungsten alloy materials, although the institute does not have a large number of high-purity tungsten metal, this has to wait for Zhang Yi to study it.
However, through high-cost processing methods and repeated smelting, they can also obtain some tungsten metal that can barely meet the standard, and make do with it first.
However, the experimental results during this period were very unsatisfactory, not to mention that the experimental indicators did not meet the requirements, and the experimental methods did not know whether they were correct.
Director Wu frowned and said: "This project is too important to us, it is a project personally arranged by the leaders of the ministry, and I think everyone should know in their hearts that we are to blame for not being able to do the experiment." ”
After hearing Director Wu's words, the scene was suddenly a little quiet, only the smoke was still drifting, and everyone seemed reluctant to make a little sound, for fear that Director Wu's eyes would fall on them and let them express their opinions.
At this time, I don't know who said: "Zhang Yi is so powerful, he can make tungsten and molybdenum separation, I don't know if he can do this?"
