Chapter 168 I'm not pretending anymore. I'm going to show my cards.
After completing a new round of simulation tasks within Shen Ye’s group, he submitted the data to the higher authorities once again.
Compared with the last time, the amount of data this time is more detailed, basically simulating all nickel-based alloy coatings of different specifications.
Having said that, the experiment still did not make any major breakthroughs in essence.
Fan Liangzhong once again tactfully conveyed to Shen Ye that Su Yiguo was dissatisfied with the simulation results.
Shen Ye had no choice but to consider changing to different nickel-based materials and conduct the simulation experiment again.
On Xu You's side, he had a new idea about titanium-aluminum alloy.
Xu You tried to add other elements to the titanium-aluminum alloy to improve the properties of the alloy.
Other elements Xu You could think of included chromium, silicon, nickel, and so on.
After adding new elements to the titanium-aluminum alloy, Xu You also simulated the material again.
According to Xu You's theory and simulation results, adding these elements can not only appropriately reduce the aluminum content, promote the formation of a uniform and dense Al2O3 oxide film, but also effectively prevent the diffusion of oxygen into the matrix.
Moreover, it is less brittle and has better plasticity than binary titanium aluminum coating.
In this way, titanium alloy can be used at higher temperatures.
After completing the simulation test of material properties, Xu You again turned to Xu Zhou for help in conducting real material experiments.
After all, the simulated situation may not be exactly the same as the actual experimental phenomenon.
There may be different degrees of differences from the actual experimental results due to inaccurate simulation conditions.
Of course, the benefits of simulation are also obvious.
If the simulation is accurate enough, it can save a lot of experimental funds and avoid conducting many unnecessary experiments.
After receiving Xu You's request, Xu Zhou once again readily agreed to help Xu You conduct the experiment.
Although there are more types of materials designed this time, Xu You has already limited many conditions to a very small range through simulation in advance, so the entire experimental volume is still not large.
Not many days later, Xu Zhou fed back the experimental data to Xu You.
Just as Xu You expected, after adding these elements to the titanium-aluminum alloy, the performance of the coating material was indeed much better.
By adding different elements, the characteristics of the materials presented are different, but they are all very positive optimizations.
After receiving Xu Zhou's conclusion, Xu You finally gained confidence to achieve better coating effects by changing materials.
Xu You just wanted to find a suitable opportunity to report his achievements to his superiors.
On this day, Fan Liangzhong came to Shen Ye's office again.
Seeing Fan Liangzhong coming over, Shen Ye also smiled bitterly, knowing that it must be Su Yiguo who asked Fan Liangzhong to rush for the result.
"Professor Shen, Chief Engineer Su means that if it doesn't work, we can try other materials. If nickel-based alloys don't work, there are other alloys that can be studied."
Shen Ye was also somewhat helpless when he heard this.
"Engineer Fan, nickel-based alloy coating is definitely the most mature coating now. It's not impossible to use other types of coatings, but if you want to study them, the cycle required will definitely be very long. It may take several months to produce any results."
Fan Liangzhong was well prepared for this.
"What Chief Engineer Su meant is that time is not a problem. Anyway, our future projects will take several years or even more than ten years. We can't always stick to the same material."
Shen Ye thought, this is not what he said when he was urging us before.
"Okay, I understand. Let's prepare for the research and development of new materials."
Xu You had been standing nearby, listening carefully to their conversation.
At this time, Xu You felt that the time was very ripe and he no longer hesitated.
"Engineer Fan, Teacher Shen, can you consider titanium-aluminum alloy coating?"
Hearing Xu You's voice, everyone subconsciously looked at Xu You.
Because Xu You rarely speaks in the office, his sudden speech this time did surprise everyone.
Fan Liangzhong had never heard Xu You's voice before, he had only seen Xu You's face and had some basic understanding of Xu You's affairs.
"Ah, Mr. Fan, this is Xu You, an intern from Ji University, a very outstanding student."
Shen Ye was worried that Fan Liangzhong didn't know Xu You, so he went out of his way to explain it to Fan Liangzhong.
"Well, Mr. Shen, I know him. It's really not easy for the leader of the Space Agency to personally invite him here."
Although Fan Liangzhong said this, it was mostly out of courtesy.
After all, he is just a freshman, not even majoring in aviation. He comes here for an internship rather than a visit.
At this time, Hu Shucheng also tried hard to signal Xu You with his eyes, asking Xu You not to ask too many questions about these things.
Hu Shucheng knew that Xu You must want him to provide some help to the project.
Doesn’t Hu Shucheng himself want the same thing?
But given their status, they would most likely just cause trouble and end up getting criticized.
What they can think of, the big guys above must have also thought of.
Sure enough, after Fan Liangzhong praised Xu You for a few words, he immediately changed the subject.
"Xu You, you are right. Titanium-aluminum alloy can indeed be used as a coating for aircraft engines. But it also has some limitations, such as not being able to withstand high temperatures. So in terms of comprehensive performance, nickel-based coatings are better."
Fan Liangzhong's answer was exactly what Hu Shucheng expected.
Hu Shucheng knew that Xu You had read a lot of books these days and must have some knowledge of aviation.
But compared with experienced aerospace engineers, Xu You's knowledge is definitely not enough.
Xu You was prepared for Fan Liangzhong's answer, and then said:
"What if we add some other elements to the titanium-aluminum alloy?"
Hearing Xu You's words, everyone was stunned for a moment.
"Yes, that is indeed an idea. Professor Shen, I think we can indeed explore in this direction."
Fan Liangzhong also expressed his affirmation, but it was not known whether he was sincere or just joking.
Hu Shucheng vaguely felt that Xu You did not seem to say these words on the spur of the moment, but rather had them prepared in advance.
Because according to Xu You's character, he would never be so rash unless he was absolutely sure.
Several PhDs in the office did not dare to express their opinions easily on this matter.
They all remembered that Xu You had once made CFD software by himself.
This student, who was much younger than them, possessed powerful abilities far beyond his age.
At this time, Xu You also planned to reveal his cards directly.
"I have done some research recently. Mr. Fan, Mr. Shen, I'd like to ask you to give me some advice."
