Chapter 189 Steel materials that can be used in fighter planes
But Ning Chen also has full confidence in himself. In terms of real ability, he is no worse than these academicians and professors, and on the contrary, he has many unique features of his own. advantages.
This also made Ning Chen accept Cheng Zhong's proposal by default, hoping that he would not let down the academician's trust.
......
In the following days, the project team once again optimized the smelting and processing technology of this steel according to the problem solutions proposed by Ning Chen and others.
What makes everyone very happy is that several process improvement plans proposed by Ning Chen have achieved very good results.
Although the various conditions proposed by Ning Chen are not so precise, they still fall within a very close range.
After another stage of experiments, the structure of the steel samples processed by the project team is closer to Ning Chen’s ideal design structure than the steel samples of the previous stage.
"Ning Chen, our improvement plan this time is very successful. Compared with the first batch of steel samples, we have solved most of the existing problems."
Ning Chen is also very satisfied with the results achieved by the project team at this stage. Steel of this level already has certain application potential.
After completing the testing of the microstructure of this batch of materials, we continued to conduct comprehensive tests on the performance of this steel material.
In order to better reflect the performance level of this new steel material, the project team specially selected steel materials used in current aerospace and aviation equipment.
Such an intuitive comparison can make a very clear comparison of the differences and gaps between the two.
Ning Chen is very much looking forward to the next experimental test, because this can basically determine whether the steel material he designed has great application value.
After formulating the plan for the test experiment, Cheng Zhong called the project team members together to explain the arrangement of various test tasks and assign tasks.
"The steel on my left is the special steel used in our current fighter aircraft, and the steel on my right is the new high-strength steel material we created in the previous stage of experiments."
The steel materials used in these active fighters are all national top-secret materials, and Ning Chen had not been able to obtain detailed information about these materials from the Internet before.
Cheng Zhong first arranged for two people to conduct a corrosion resistance experiment on two steel materials. Because this experiment will take a long time, obvious comparison results cannot be obtained in a short time, so it is necessary to conduct it as soon as possible. Go and start experimenting.
As for the remaining properties such as strength, microstructural characteristics, wear resistance, fatigue resistance, toughness, etc., the measurement speed will be much faster.
Cheng Zhong did not arrange any testing and experiment tasks for Ning Chen, but took Ning Chen with him to check other people's testing work.
This is also a special treatment given by Cheng Zhong to Ning Chen. After all, the establishment of the entire project team came from Ning Chen's design plan. At this time, it is time for Ning Chen to enjoy the joy of success.
Ning Chen really wanted to do some measurements by himself, but it would be nice to be able to witness various measurement results earlier.
As the experiment progressed, the strength data of the two steel materials came out soon.
"Academician Cheng, after testing, the yield strength of the special steel for current fighter aircraft is 1506MPa, while the yield strength of our new steel material is 1610MPa!"
Hearing this data, Cheng Zhonghe Ning Chen felt very excited.
Although the yield strength of the new steel is only 100MPa higher than that of the steel used in current fighter aircraft, this improvement is enough to be considered a significant breakthrough in the field of aerospace equipment.
What's more, this new type of steel material has only just gone through the second stage of experimentation, and there is still some room for progress.
Ning Chen is confident that if one or two more stages of research are carried out, the yield strength of this steel material can be continued to be increased by about 100MPa on this basis.
After that, other test data of these two steel materials were also released one after another.
In multiple tests including ultimate tensile strength, elongation, area reduction, hardness, fracture toughness, etc., the new steel materials processed by the project team have achieved varying degrees of leadership. With such a result, even Cheng Zhong couldn't help but smile all over his face.
“Great, based on the current test performance of this new steel material, there is a high probability that it will be applied to the next generation of fighter aircraft, as well as other aerospace, aviation and other fields. Just look at the final corrosion resistance test What’s the result?”
In everyone’s expectation, the corrosion resistance test results have finally been released.
"Academician Cheng, after detailed comparison, the new steel material performed better than the steel material of the current fighter in the first stage of corrosion resistance test. We will further test the two materials later. Corrosion resistance, in order to obtain more rigorous results.”
Because the corrosion resistance of steel materials requires long-term testing, the data obtained now is only relatively preliminary. Data comparison.
Despite this, at least judging from the data obtained at the current stage, the new steel materials processed and produced by the project team are undoubtedly very successful!
After confirming these results, the members of the project team also briefly celebrated together, feeling happy for everyone's achievements.
As a scientific researcher, in fact, every day’s research life is relatively monotonous, and you also have to face various pressures such as failed experiments.
But the success of every experiment can greatly boost the mood of researchers and make them feel that their efforts these days are valuable.
After the short celebration, the project team did not stop their research, but continued to analyze the experimental data on this basis, summarize the problems that emerged, and propose improvement plans.
Ning Chen was once again the last person to conclude, and proposed some new improvement methods that might improve the properties of this new type of steel material.
……
To the joy of the members of the project team, after the third stage of experimental improvement and testing, the performance of this new steel material is indeed in line with everyone’s expectations. expectations.
Compared with the test results of the second stage, the steel materials after the optimized process plan showed better data in various performance tests.
At this time, Ning Chen could no longer think of any room for further improvement.
The next work that needs to be done is to study the batch processing technology of this new steel material, and such work can only be carried out in steel plants.
Ning Chen knew that at this stage of the research, he had completed all the work he could do.
During the break, Cheng Zhong and Tian Shihao found Ning Chen and discussed with Ning Chen the future applications of this new type of steel.
“Ning Chen, through our three stages of research, we have basically determined that this new type of steel can be used in aerospace, aviation and other fields. However, our existing work is not enough. Next, we will continue to enter the steel plant and study batch processing technology with the scientific researchers of the steel plant. I wonder if you will continue to participate in the project with us?”
“Academician Cheng, Professor Tian, I will not participate in the subsequent research work. My area of expertise is mainly in material design and batch processing technology. I really don’t know much about it, so it is difficult to contribute to the research of the project.”
In fact, if Ning Chen had been allowed to stay in the steel factory for a few months, he would have figured out all these things sooner or later.
It’s just that Ning Chen still has other topics to study, and he can’t devote too much energy to the field of steel materials.
This time, Ning Chen’s goal was just to move the system reward information into the real world, and what Ning Chen has done now has already achieved his goal.
"Well, this research project did last for a long time. Whether you continue to participate in the project is completely according to your own wishes."
Ning Chen expressed it tactfully , after they no longer participated in the subsequent research work of the project, both Cheng Zhong and Tian Shihao expressed their understanding of Ning Chen's decision and did not interfere with Ning Chen's choice.
"Academician Cheng, Professor Tian, if there is any need for me in the subsequent research work, I will go to the research site immediately."
"Well, Ning Chen, you can have this intention That’s great. Of course, we won’t bother you unless there are special circumstances. We old guys still have some value.”
