After a thousand years of trading, start a million barrels of oil

Chapter 196 Let the process speed up

Jiang Fan didn't expect Academician Ma Weiming to ask for himself this time, and Jiang Fan was somewhat flattered to receive such a request from a boss of this level.

He thought about it. He originally wanted to research the two materials of high temperature resistance and heat insulation. For the most primitive application target exoskeleton, the high temperature resistance of some joints and other delicate parts is equally important for the heat insulation of the human body. Therefore, both parts need to be developed for easy application.

According to Mr. Ma, the electromagnetic gun is more inclined to have the property of high temperature resistance, so from the perspective of overall efficiency, it is undoubtedly more cost-effective to develop high temperature resistant materials first, so that this achievement can be put into practical use faster. Than.

After figuring this out, Jiang Fan didn't hesitate, looked at Ma Weiming and said, "I'll do my best!"

Back in Fan's laboratory, Jiang Fan started the research and development of tungsten-carbon alloy high-temperature resistant materials.

Although there was a formula given by the young man, due to the age, the young man told Jiang Fan that he found elements of the material from a photo taken by someone, but the paper recorded in the photo was somewhat incomplete.

There should be one or two elements missing, and Jiang Fan needs to make up for it himself, which is why he set up a laboratory, just to do the work of making up for it.

Secondly, even if there is no shortage of elements, the production process must be explored and studied. For example, the same raw material ratio, after different forging, stamping, baking, stretching and other processes, the properties of the obtained materials are completely different.

This is a bit like stir-frying. What is the ratio of meat, vegetables and various seasonings? This is the recipe.

But with the same recipe, different chefs can produce very different things, because it also involves the length of frying time, the order of adding raw materials, the mastery of the heat and so on.

All these combined can produce a delicious meal.

Therefore, materials science has logic and rules to follow, but at the same time it is very boring, because the process of research and development is filled with countless enumerative exclusion tests until the material that meets the requirements is encountered.

When Edison invented the electric light, he tried one by one. After trying more than 1600 materials, he finally found carbon filament, a material with good performance and price.

Although modern materials science has a lot of theoretical guidance, it still cannot escape this process.

Therefore, Jiang Fan led the team to conduct a characteristic research on the high-temperature-resistant tungsten-carbon alloy material formula, and then arranged for them to mix in a large number of other materials one by one, and began to do exclusion tests and other tests.

He reckoned that he already had the main formula, and there should be some major breakthroughs in about a month.

However, the actual results are not ideal, and the overall promotion progress is slow.

Jiang Fan also discovered this problem, and called the person in charge of material testing over to ask, "Why is it so slow?"

The person in charge also said helplessly: "There are too many possible materials, and we need to conduct a long time of testing in each case to determine its properties, so it is difficult to have too many materials for now. Advance quickly."

Jiang Fan was puzzled: "Isn't there a 'Materials Involved Permission Database'? The complete characteristics of various materials should be marked on it. If you directly refer to it for screening, you should be able to exclude many directly, and it won't take so long."

'Materials related to allowable data' refers to the mechanical property data of various materials at different temperatures, and the oxidation/corrosion performance data under various conditions.

It also includes special environment service data and physical and chemical properties, such as erosion resistance, density, thermal conductivity, thermal expansion coefficient, etc.

These allowable data are obtained from multiple batches of measurements through correct test methods, and a confidence interval is also given.

With these data, many materials do not need to be included in the test, and can be excluded by directly looking at the allowable database parameters, so the materials that need to be tested should be limited.

The person in charge took out his mobile phone to operate, and found the officially authorized permission database with the confidentiality level and pointed it to Jiang Fan: "Our country has such a material database, but it is not comprehensive.

Moreover, some data are actually inaccurate due to short test time, incorrect test methods, or insufficient test sample size.

Therefore, in order to ensure the accuracy of the experiment, we still need to conduct secondary tests on many ambiguous materials.

Moreover, the test already needs to detect its performance in a longer period of time, which will also delay a lot of time. "

Jiang Fan didn't expect this point. He didn't have trouble with the formula and technology. He didn't expect that the progress would be greatly delayed due to the imperfection of a basic database.

Sure enough, in many cases, scientific research is not all high-level things, and the accumulation of some details can often play a vital role.

And it also made him think of some other problems. The previous CNC machine tools included lithium batteries, and there were also problems that specific components, including the whole machine, had to be tested for a long time to verify their performance and reliability.

And this is why we lag behind others in many fields but catch up with difficulty, because the huge amount of time spent on some basic testing work cannot be avoided.

For example, we are 30 years behind others in the field of aircraft engines, and most of the research and development work is used in the testing process.

The life of an engine needs to reach tens of thousands of hours, which is about one and a half years.

In order to be safe and ensure nothing goes wrong, you have to let it run 24 hours a year without stopping for a year to test, otherwise, who would dare to sit without such a complete test?
And if there is a problem in 9 months, then adjust the plan and start from scratch for another year and a half.

So why is there a difference of 30 years, more than 95% of the time is spent on testing.

If this problem can be solved, and some means of saturation testing can be moderately added, the 30-year period can be reduced to 3 years, or even one year.

Therefore, the lack of testing methods is the key to restricting long-term breakthroughs in many fields.

Including the material mentioned by the person in charge, which involves a licensed database, a large amount of material requires a long period of testing before it can give relatively accurate and comprehensive data.

If there is a way to shorten this process and quickly complete this basic material library, it will be a leap forward for the entire material industry in China, and many scientific research results will spring up like mushrooms after rain.

But how to do it?
Jiang Fan felt that he had to find young people to see if there was any better way for future technology in this regard.

After making the decision, he ended the discussion with the person in charge in front of him, returned to his office, summoned the bracelet, entered the trading space, and called out the young man.
