Spark

After bidding farewell to Guo Qi, Chen Nian quickly returned to his residence.

He couldn't figure out how this happened.

Of course, in the past, he also encountered a rapid decline in the number of system demand sources, but none of the declines could reach such an exaggerated level.

From thousands of points, it dropped to double digits at one time.

Undoubtedly, this represents a major breakthrough in the technology of the first wall material within Huaxia and within the range that Chen Nian can obtain.

Moreover, this so-called breakthrough is likely to not only stay at the theoretical level, but directly become "usable".

What are you doing?

The Huorong team has only been established for more than a month, and the problem has been solved?

The whole thing is absurd, but it seems quite reasonable.

After all, his own group is not the only one working on this stuff.

In theory, it is possible for any group to make progress at any time.

But the problem is, this thing happened a little too suddenly.

It is not that Chen Nian has not paid attention to the theoretical progress of the first-wall materials during this period, but in his impression, the domestic groups seem to be far from the real results.

So who is it?

He immediately opened arXiv and searched for the content of the first wall material, but the result was only the results on tungsten alloy released by the United States some time ago.

Obviously, it is impossible for this thing to reduce the source point requirement of the system to 12 points.

Chen Nian frowned. He picked up the phone and called Chen Guo. After connecting, he immediately asked:

"Professor Chen, can you help me pull out a list of domestic groups that are working on first-wall materials?"

"If you can, it would be better to expand the scope to include all groups related to high-temperature-resistant, radiation-resistant materials."

Chen Nian's expression is very rigorous. Such a requirement is actually based on the randomness in material science research.

You can't guarantee that what you make will meet your expectations every time. It is very likely that you just want to make a cheap diamagnetic material, but what you end up burning is a room temperature superconductor?

Of course, it is not impossible to simply create a high-temperature-resistant material, but due to some unknown changes in the twin boundary or grain boundary structure, a radiation-resistant material with radiation repair properties is produced.

Therefore, including all relevant groups is the safest method of exclusion. Although it may take more time, at least it can avoid mistakes, omissions and misjudgments.

After hearing Chen Nian's words, Chen Guo didn't understand his intention immediately, but asked subconsciously:

"Is Tinder's current manpower insufficient?"

As soon as these words came out, Chen Nian didn't know how to reply.

Say you want to find a group that might have already made the first wall material?

In the absence of a source, this kind of information should not be disseminated at will to avoid unnecessary interference.

So he simply replied:

"It's not that there are not enough people, I want to absorb some new information——yes, I also need to ask you to help collect the latest results of these groups, and give them to me after they are consolidated."

"It is estimated that the number will not be small."

Chen Guo replied.

"It's okay, let's take a look."

Hearing this, Chen Guo didn't say any more, but quickly set a time with Chen Nian, and expected to give him the list within three hours.

Putting down the phone, Chen Nian let out a deep breath.

In a sense, materials science is indeed the scientific research field that best embodies a country's "national destiny".

It is very likely that just because of an accidental random event, the entire country will achieve leapfrog development in a very short period of time.

This is the case for the first wall material, maybe the room temperature superconducting material is also the same?

If there is no industrial method for making metal hydrogen materials in advance, will one day, driven by a certain opportunity, domestic researchers will come up with better things?

It's not impossible.

A trace of regret flashed in Chen Nian's heart, but he regained consciousness in an instant:

Some seemingly accidental things, in fact, may not be accidental.

If there were not many previous attempts on high-temperature resistant materials, I am afraid that such "luck" will not appear in another ten years.

Thinking of this, Chen Nian's heart settled down again.

Although there are indeed many accidents and randomness in the process of the development of human science and technology, in general, it still follows a set of fixed and unique laws.

The disturbance I caused was great, but it was not so great that it would cause human beings to enter a black humorous plot similar to "Astray".

What is the nature of this incident, the answer will be revealed when Chen Guo feeds back the list and finds the "God-sent material".

Chen Nian thought for a moment, and finally spent 12 original computers in the system to analyze all the technologies of the first wall material.

The information transmission process this time was not long. In less than an hour, all the information about this material had been clearly presented in his mind.

And when the series of chemical formulas appeared in front of his eyes, he actually had a feeling of enlightenment.

No, the method of making the material is not simple.

On the contrary, it is extremely complex - but extremely "directive".

First, nickel, chromium, cobalt, and iron elements are used to make the Cr9FeCoNi high-entropy alloy that has been verified to have good performance, and then it is chemically bonded with graphene prepared by vapor deposition method by atomic layer deposition method, and finally thermal In the isostatic pressing process, boron boron nitride is used for surface treatment of the composite material obtained in the previous stage.

Not to mention the follow-up steps, the sintering treatment of high-entropy alloys alone involves great uncertainty.

In the last life, Chen Nian once heard a very classic case. In a laboratory, a brother had done experiments for 6 years and burned more than 1,500 furnaces of materials. Finally, he fixed a relatively stable parameter, and immediately It was about to produce results, but one day I went to the laboratory again and found that the same thing could never be burned again.

After checking and checking for two full weeks, I finally found out that it was the brother who moved the gas nozzle of the horse boiler, which affected the heat uniformity.

This example is still understandable. What is even more exaggerated is that sometimes the number of samples put into the furnace at the same time will also affect the final result.

Who are you going to reason with?

Therefore, the craftsmanship itself is definitely complicated, and the reason why it is said to be "directive" is because this material simply synthesizes the advantages of all single ingredients.

The thermal stability and deformation resistance brought by the large number of atomic coordination and lattice defects caused by the complex crystal structure of high-entropy alloys, the damage repair ability brought by the single-layer structure and high two-dimensionality of graphene, boron boron nitride own radiation resistance.

Under such a combination, the high-entropy alloy-ceramic composite material can achieve high temperature resistance and radiation resistance performance, which far exceeds the limit that a single material can exert.

Sure enough, it was a genius design, and it was also the result of great luck.

Chen Nian shook his head with emotion, then turned and walked into the bathroom.

After a busy day, it's time to take a bath and rest

Two hours passed by, and Chen Nian had just finished washing when he received a list from Chen Guo.

The list of more than 400 made Chen Nian dazzled, but fortunately, no more than 20 groups released new results within a month.

After selecting these groups, Chen Nian began to examine them one by one.

The first step he did was to exclude those who had published preprints on arXiv and had already read the papers.

After some operations, there were only 9 remaining groups. Without exception, the results of these groups were not systematically elaborated. They just gave some brief introductions to relevant personnel during the collection process just now.

However, even with a simple introduction, Chen Nian still found the answer he wanted at a glance.

"A new type of high-entropy alloy material with high temperature resistance, creep resistance, and radiation resistance is still in the verification stage, and the radiation resistance performance is not supported by actual test results."

Looking at the group name again, as expected, regular army.

Wu Tao's group in the Laboratory of Radiation Mutagenesis and Materials Computation, University of Science and Technology of China.

Although Chen Nian has not had much contact with him, and Xinghuo has not directly cooperated with this laboratory before, Wu Tao's status in the field of radiation-resistant materials is still unquestionable.

In the last life, the series of awards he won were considered extremely dazzling among his peers, but in this life...his progress seems to be faster?

Without too much hesitation, Chen Nian immediately called Chen Guo and booked a trip to AH.

This meeting should be of great significance to the EAST project.

It can at least speed up the progress of the entire project by more than 6 months, and it is even more immeasurable from the perspective of the historical process of "mankind masters nuclear fusion".

At the same time, Wu Tao was sitting in his office in the materials laboratory of the University of Science and Technology of China, holding the latest XRD test results in his hand.

The assistant on the opposite side was full of excitement, dancing and reporting the latest progress:

".This is the data we want. What you see now is the XRD pattern, followed by the joint characterization of sEM and XRD. All of them have been run. It can be said that it is completely in line with expectations."

"The test results are also very good. It can withstand high temperatures of 3400 degrees, and its creep resistance is better than that of several materials commonly used today."

"It can be said that this thing is guaranteed to be a new type of high-temperature-resistant material, but the cost is too high. If it wants to be applied in the aerospace field on a large scale, it is probably not as good as the previous achievements of the Spark team."

"But it's not important. We have to look at the problem from the perspective of development. Now the critical point of the official productivity explosion, after the normal temperature superconducting materials are rolled out and nuclear fusion is born, the cost of new materials will plummet."

"Its significance is definitely not 'realizing nuclear fusion' itself. Of course, this alone is actually enough."

Hearing his words, Wu Tao nodded calmly, and then asked:

"EAST, have you got in touch? When can the anti-radiation experiment start?"

The assistant shook his head and replied:

"Contacts have been made, but the specific schedule has not yet been determined."

"The only equipment we can use now is the HT-7 that was eliminated from the EAST project, but the schedule will be at least two months later. I think we can send a preprint first to occupy a place?"

"What's the use of this!"

Wu Tao replied with some amusement.

The little thought of my assistant is actually clear. Don't you just feel that after working for so long, it's hard to produce results, and you have to announce it quickly to satisfy your sense of accomplishment?

This kind of mentality is understandable, after all, the group has suffered enough in the past few years.

Staying up late and working overtime without holidays is not a problem. What is more painful is the mental and psychological torture.

You never know where the future is, and you don't know whether your choices are meaningful.

Seeing that the classmates who came out of the same class have already entered the society, got a lot of income, drove a luxury car, and lived a life of a superior person, but you still spend the whole day in the lab. In the living room, not to mention the young people have a gap in their hearts, even if they have already achieved fame, they are actually a little depressed.

More importantly, in the past few years, the general environment has also changed.

The remuneration of scientific research personnel has been continuously improved, and the funding has been increasing year by year. In the past, they could scold the government and find some comfort for themselves. Now?

People have indeed done it well, and if they can't make it, then it's really their own problem.

Therefore, this new material is really life-saving for the laboratory.

It's no wonder that everyone can't wait for the release of the results.

However, as a mature scholar, you should be cautious about bringing your own achievements.

So he continued:

"The most important feature of this material is the anti-irradiation part, so we should be cautious before performance verification."

"However, two months is really too long. How about this, I'll go find someone to see if I can get a plane. Until there is a result, you all stay honest and continue to optimize."

"I don't need to say how meaningful this thing is. I hope that once we take it out, it will be a mature and usable thing, and it can be directly used in the EAST project. Understand?"

Hearing his words, the assistant nodded helplessly.

——

Anyway, it's not too late, just wait and wait.

He put away the scattered documents on the table, and planned to return to the laboratory to continue to burn the stove, but at this moment, the phone on the table suddenly rang.

Wu Tao on the opposite side picked up the phone, and after hearing the first sentence on the opposite side, his expression quickly became serious.

".Yes, I am."

"No need to verify? How is this possible!"

"Ah, I see. I see. When?"

"Okay, understand, we'll be ready."

"Are you sure? We don't have much confidence yet."

"Okay, that's it!"

After hanging up the phone, Wu Tao looked at the assistant who was still standing aside with a relieved smile on his face.

"The problem is solved."

he spoke.

"Solved? Has HT-7 been approved?"

Wu Tao shook his head and replied:

"It's not approved. It should be said that it belongs to us."

"The Spark team has our information, and they believe this material is the final solution."

"So, starting today, all other testing work on HT-7 has been suspended and allocated to us."

"In the next month, all departments will cooperate with us to optimize new materials!"
