As a top expert on titanium alloys in China, Cao Dongming attaches great importance to the achievements in the field of titanium alloys because he knows how widely used titanium alloys are in the aviation field.
Cao Dongming is a researcher at the Institute of Aeronautical Materials and a technical expert affiliated with the Aviation Group. He has participated in the manufacturing of advanced fighter aircraft and understands that one of the general directions for the development of fighter aircraft is to use titanium alloy materials to replace heavier alloy materials.
For example, steel.
No matter what kind of steel, the density is very high, and the density of titanium alloy is only 60 or 70% of steel, and the hardness is no less than steel, so it is naturally the first choice material to replace steel.
In the aviation field, there are two research and development directions for titanium alloys. One is to reduce costs, and the other is to manufacture titanium alloys for various uses to meet the needs of various aircraft components.
Most parts on the aircraft require alloy materials, including the casing, engine, rotating shaft, landing gear, etc. If all are made of titanium alloy, the weight will be 20 to 30 percent lighter to achieve the same performance.
, not only is it fast and has high load-bearing capacity, it also becomes more flexible.
If you want to meet the needs of various aircraft parts, you need to manufacture various types of titanium alloys, so you need to have enough understanding of titanium alloy manufacturing.
So how can we increase understanding?
This requires more materials research projects similar to "super-stress resistant alloy materials".
The research and development related to increasing the strength of β-type titanium alloys is a major research in the field of titanium alloys. Because of its importance, the National Natural Science Foundation of China will provide support.
Increasing the strength of β-type titanium alloy does not seem to solve a single problem, because there are many influencing factors. It can be said that there is no definite direction, and each research can only be used as a reference.
However, if a certain research can produce an "ultra-high-strength titanium alloy" using conventional means, it means that it is "very close" to the right direction, and it will become very valuable as a reference.
The titanium alloy that is now manufactured with a tensile strength of 1560 MPa is the kind of research that has achieved very significant results.
Because of this, Cao Dongming attaches great importance to it.
After he and Peng Hui learned about the research and development process, they went directly to the data analysis office. He was very interested in Wang Hao's specific analysis.
This may be able to be applied to other research in the field of titanium alloys.
After arriving at the data analysis office, there was nothing more to do with Peng Hui. Wan Yiming, who was in charge of data analysis, explained to Cao Dongming.
Wan Yiming has been studying Wang Hao's data analysis for a long time, and has fully understood 80% of the previous content.
He explained it very carefully.
Cao Dongming kept nodding while listening and understood the analysis process. When the calculation analysis was explained, Wan Yiming stopped talking.
"Continue talking?" Cao Dongming raised his head and was confused.
Wan Yiming smiled awkwardly and said, "Professor Cao, I don't fully understand the last part."
"ah?"
This answer was quite unexpected.
Cao Dongming was not from the metal laboratory, so he couldn't say anything directly, so he nodded and said, "That's it, you go about your business first."
"Okay~~"
Wan Yiming felt very embarrassed and quickly walked away to continue his analysis and understanding.
Peng Huizheng walked to the side.
Cao Dongming couldn't help but whisper to Peng Hui, "The materials analyst in your laboratory is not very good." He kept shaking his head as he spoke.
"yes!"
Peng Hui nodded vigorously in agreement.
He really felt that Wan Yiming's level was very poor, and the data analysis during the entire research process was not as helpful as Shi Guifang, who did data calculations. However, he still knew that every laboratory must have data analysts.
Wan Yiming still has some achievements in the theory of data mining. It is not easy to find someone with the same level.
Cao Dongming sighed with emotion, and then began to look seriously. He was already over fifty years old. He knew a lot about every aspect of the research on the titanium alloy project, and he could know the methods even for complex data analysis.
Ten minutes have passed...
Twenty minutes have passed...
Cao Dongming felt that he might be in a bad mental state, so he rarely asked his doctoral students to help him make a cup of coffee. He drank coffee very rarely, mainly because of his living habits, but now he must drink a cup of coffee to refresh himself.
Then, another hour passed.
Cao Dongming sat on the chair with an expressionless face, staring at a pile of codes and annotations on the computer, looking left and right while thinking.
Finally he stood up and went to Peng Hui's office.
Peng Hui quickly stood up and asked, "Professor Cao, how are you doing?"
"Ahem."
Cao Dongming touched the corner of his mouth and said, "I just thought about it. It would be better for data analysis to be done by specialized people."
"I came mainly to understand the implementation process."
He said it and nodded in agreement very seriously, as if that was what he was thinking in his heart.
Peng Hui agreed, "Yes, I think so too, so I never get involved in complex data issues."
Cao Dongming continued to agree, "That's it. When we lead a team to do projects, the most important thing is to grasp the general direction and let everyone in the team perform their duties..."
…
the other side.
Wang Hao continued his data analysis work.
Three courses a week brought an inspiration value of 31 points, allowing the inspiration value to break through 100 points again, and then he had a brand new analysis method, targeting some data that had not been analyzed before.
After you have an idea, record it and do research immediately, and try to complete the work at hand as soon as possible.
He spent a whole day completing the new code, and then went to the computer lab to borrow a server for calculations.
The amount of calculation this time was less than the last time, but he still applied for 5,000 yuan in funding to pay for the use of the server.
Chen Qinghua could give him a hundred thumbs up for what he did. He felt that Wang Hao was very principled in doing things. He used the equipment in the computer laboratory to calculate the research content of other teams. Normally speaking, he did have to pay a certain fee.
The little old man had a lot of admiration in his heart, but he still had to exchange pleasantries verbally, showing that he accepted it out of helplessness.
This approach can be described in two words as ‘hypocrisy’.
Of course, similar things can also be described as etiquette. The cultural tradition of Chinese people is to be modest and polite. If you have any thoughts, express them directly, which is not etiquette.
Wang Hao didn't think so much. He insisted on his principle and must give the money to the computer laboratory and use their servers for calculations, which was an honest use.
This will make you feel very comfortable.
After entering all the codes into the computer and officially starting the calculation, Wang Hao also breathed a sigh of relief. Although the calculation results have not yet come out, after completing the calculation and summarizing, the analysis can be completed.
This research was finally completed, and what he was looking forward to was that the A-level difficulty research could add an additional thousand teaching coins.
The last research on the Mersenne prime number algorithm also brought a harvest of one thousand teaching coins.
【Teaching Coin:5597.】
If we can add another thousand teaching coins, two-thirds of the goal of tens of thousands has been achieved.
"Only one-third is left. The Long March has gone so far..."
"But we still have to keep walking!"
…
On the same day, an expert review team temporarily formed by the Department of Materials Science came to the Metal Laboratory of Xijing Jiaotong University.
This expert review team is composed of seven expert members, including Cao Dongming who arrived first, and the others are also experts in the field of metal alloys from various universities and institutions.
They originally didn't want to come so early, and the scheduled time was next weekend. However, Cao Dongming came first, and they had no choice but to follow.
Everyone in the expert review team was interested in research in the metal laboratory. After arriving, they were as concerned about the research issues as Cao Dongming. After sorting out the entire research process, they found that there were no problems, so they planned to take it with them.
The manufactured alloy is sent back for testing.
"This should be the final result, right? Our laboratory can prepare for settlement."
A leading expert said.
He is Li Jiping, 61 years old, a top expert on non-ferrous metals, a professor at Capital University, an academician of the Academy of Sciences, and the leader of the expert review team.
The expert review team comes here to conduct an audit. If they find that there are no problems with the research, they can take the final product back for testing while waiting for a detailed report from the metal laboratory.
After a series of approvals and seals, the project can be settled.
The subsequent conclusion has nothing to do with the expert review team.
To be continued...
