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 has also encountered a rapid decline in the number of system demand sources, but no one has such an exaggerated decline.

From thousands of points, it drops to double digits at once.

There is no doubt that this represents a major breakthrough in the technology of the first wall material within Huaxia and within the scope 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 the.

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

It's all absurd, but it seems reasonable.

After all, it's not just your own team working on this thing.

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

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

Chen Nian did not pay attention to the theoretical progress of the first wall material during this time, but in his impression, the domestic group seems to be far from the real results.

So who the hell is it?

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

Obviously, it's impossible to reduce the system's source requirement to 12 points.

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

"Professor Chen, can you help me pull up a list of groups that are making the first wall material in China?"

"If you can, it's better to expand the scope to include all the groups that are concerned with high-temperature, radiation-resistant materials."

Chen Nian's expression is very rigorous, and such a requirement is actually based on the randomness in materials science research.

You can't guarantee that every time you make something will match your expectations, it's possible that you just want to make a cheap diamagnetic material, but what happens to be a room-temperature superconductor?

Of course, it is not impossible to simply want to make a high-temperature resistant material, but because of some unknown change in the structure of twin grain boundaries or grain boundaries, it is not impossible to develop an anti-radiation material with radiation repair properties.

Therefore, including all relevant groups is the safest way to exclude, although it may take more time, but at least it can avoid mistakes, omissions and miscalculations.

After hearing Chen Nian's words, Chen Guo did not understand his intentions at the first time, but subconsciously asked:

"Is there not enough manning for the velvet at the moment?"

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

Say you're looking for 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 is not enough manpower, I want to absorb some new information-—— right, and I have to trouble you to help collect the latest results of these groups, and give them to me after a unified summary."

"That's probably not a small number."

Chen Guo replied.

"It's okay, let's take our time."

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

Putting down the phone, Chen Nian exhaled deeply.

In a sense, materials science is still the scientific research field that can best reflect a country's "national fortune".

It is quite possible that just because of a random event, the whole country will develop by leaps and bounds in a very short period of time.

This is true for the first wall material, and perhaps the same is true for the room temperature superconducting material?

If we hadn't made the industrial manufacturing method of metal hydrogen materials in advance, would one day, under the impetus of a certain opportunity, domestic researchers would come up with better things?

It's not impossible.

A trace of regret flashed in Chen Nian's heart, but he came to his senses in an instant:

Some things that seem to be accidental may not be accidental.

If there were not many attempts at high-temperature resistant materials in the early stage, I am afraid that in another ten years, such "luck" would not have appeared.

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

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

The disturbance is great, but not so great that it would lead humanity into a dark humorous plot like "Alien Astray".

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

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

The process was not long, it took less than an hour, and all the information about the material was clearly presented in his mind.

And when that string of chemical formulas appeared in front of his eyes, he actually had a feeling of sudden enlightenment.

No, the preparation of materials is not simple.

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

First, nickel, chromium, cobalt, and iron elements are used to make Cr9FeCoNi high-entropy alloys with proven properties, and then they are chemically bonded with graphene prepared by meteorological deposition by atomic layer deposition, and finally boron nitride is used by hot isostatic pressing process to treat the composites obtained in the early stage.

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

In the previous life, Chen Nian once heard a very classic case, in a laboratory, there was a brother who did experiments for 6 years, burned more than 1,500 furnaces of materials, and finally fixed a relatively stable parameter, and the results were about to be produced, but one day he went to the laboratory again and found that he could not burn the same thing again no matter what.

After two weeks of investigation, I finally found out that it was the senior brother who moved the gas nozzle of the horse boiling furnace, which caused the thermal uniformity to be affected.

This example is understandable, and what is even more exaggerated is that sometimes the number of samples put into the furnace at the same time can also affect the final result.

Who do you talk to about this?

Therefore, the process itself is absolutely complex, and the reason why it is "directive" is because the material is a very simple combination of the advantages of all the individual components.

The thermal stability and anti-deformation ability caused by a large number of atomic coordination and lattice defects caused by the complex crystal structure of high-entropy alloys, the damage repair ability caused by the single-layer structure and high two-dimensional nature of graphene, and the anti-irradiation ability of boron nitride itself.

Under such a combination, the high temperature resistance and radiation resistance of this high-entropy alloy-ceramic composite material far exceed the limits of a single material.

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

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

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

Two hours passed in a flash, and as soon as Chen Nian finished washing, he received a list of Chen Guo's feedback.

Chen Nian was dazzled by the list of more than 400 items, but fortunately, there were no more than 20 groups with new results released within a month.

Having selected these groups, Chen Nian began to examine them one by one.

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

After some operation, there are only 9 remaining groups, without exception, the results of these groups are not systematically elaborated, but in the collection process just now, some brief introductions were made to the relevant personnel.

However, even if it was just 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 irradiation resistance performance is not supported by actual test results."

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

Laboratory of Irradiation Mutagenesis and Materials Computing, University of Science and Technology of China, Wu Tao's group.

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

In the previous life, he won a series of awards that were extremely dazzling among his peers, and in this life. Does his progress seem 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 speed up the process of the entire project by at least six months, and if you look at the historical process of "human mastery of nuclear fusion", it is even more immeasurable

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

The assistant opposite was full of excitement, dancing with his hands, while reporting the latest developments:

"That's the data we want, what you're looking at now is the XRD graph, followed by the combined characterization of sEM and XRD, all of which are gone, so to speak, exactly as expected."

"The test results are also very good, with high temperature resistance of 3400 degrees and creep resistance better than several materials commonly used today."

"It can be said that this thing has been guaranteed to be a new type of high-temperature resistant material, but the cost is too high, and if it wants to be used in the aerospace field on a large scale, it is estimated that it is not as good as the previous achievements of the Xinghuo team."

"But it doesn't matter, we have to look at the problem from the perspective of development, and now the critical point of the formal productivity explosion, after the spread of room temperature superconducting materials and the birth of nuclear fusion, the cost of new materials will plummet."

"It's definitely not about 'achieving nuclear fusion' per se, of course, that's enough."

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

"EAST, are you connected? When can the anti-radiation experiment start? ”

The assistant shook his head and replied:

"We have been contacted, but the exact schedule has not yet been determined."

"Now we can only use the HT-7, which was phased out of the EAST project, but the backlog will be at least two months later, and I think we can send a preprint first to take a single place?"

"What's there to take advantage of!"

Wu Tao replied with some amusement.

The little bit of caution that he thinks about as an assistant is actually clear, doesn't he just feel that he has been doing it for so long, and he has finally produced results, so he has to announce it quickly to satisfy his sense of achievement?

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

Staying up late and working overtime without holidays is not a thing, what is more painful is the mental and psychological torture.

You never know where the future holds, and you don't know if your choices make sense.

Seeing that the classmates who came out of the same class have all entered the society, got a lot of income, drove a luxury car, and lived a life of being a human being, while you are still soaking in the laboratory all day long, not to mention that there is a gap in the hearts of the young people, even if you have already achieved fame, you are actually a little depressed.

What's more, in the past few years, the general environment has also changed.

The treatment of scientific researchers is constantly improving, and the funding is getting higher and higher year by year.

People have really done it, and if they can't do it again, then it's really their own problem.

Therefore, this new material is really a lifesaver 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 results.

So, he continued:

"The most important feature of this material is the radiation resistance part, so we still need to be cautious before verifying the performance."

"However, two months is really too long. In this way, I'll go find someone to see if I can get the time, and until there is a result, you can stay honest and continue to optimize. ”

"I don't need to say how meaningful this thing is, I hope that as soon as we come up with it, it will be something that is mature and usable, and it can be directly used on the EAST project, understand?"

Hearing his words, the assistant nodded helplessly.

——

Anyway, it's not that much time, just wait.

He put away the papers scattered on the table and planned to return to the laboratory to continue burning the stove, but at that moment, the phone on the desk suddenly rang.

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

"Yes, I am."

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

"Ah, I see, I see. When? ”

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

"Are you sure? We're not too sure ourselves."

"Okay, that's it!"

Hanging up the phone, Wu Tao looked at the assistant who was still standing aside, and a relieved smile appeared on his face.

"Problem solved."

He spoke.

"Solved? HT-7 batch down? ”

Wu Tao shook his head and replied:

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

"The Spark team got our information, and they thought this material was the final solution."

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

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