Materials science is not only about ferroalloys, although ferroalloys are the most used and most widely used alloys on the whole earth, but they are not destined to be all.

In fact, various aluminum alloys and non-metallic alloys, after the Second World War, appeared in large quantities for the simple reason of the large-scale application and development of aircraft.

From rifles, artillery, machine guns, tanks, and the use of firearms, the center of gravity of the entire war is on land, even if Britain crisscrosses the seven seas and overwhelms the navy, but the real decision on the final outcome of the war is still land warfare.

World War I and World War II both had large-scale naval battles, and even in World War II, there was also a large-scale Pacific War, which was a war that spanned the entire Pacific Ocean, but these are only parts of the war, and these naval battles may be able to influence the course of the war, but they are not the final word.

However, after World War II, with the rapid development of aircraft, air supremacy has become a key factor.

When the Air Force was still in its initial development, it was like this, and when the Air Force was developed to the extreme, and by the end of the 20th century, a war that could be solved by the Air Force alone abounded.

Unlike battleships, although battleships have certain requirements for weight and volume, they are more corrosion-resistant, and these ferroalloys can solve the problem.

In the era of the Air Force, not to mention the weight of a few tons, it may even be tens of kilograms, a few kilograms of weight, have been deducted to the extreme, and ferroalloys with a large specific gravity are not very suitable, so aluminum alloys and non-metallic materials are popular in the world.

In the era of aircraft development, even an advanced aircraft, 50% of its materials are not made of metal materials, so to speak, the weight is reduced to the minimum, but the performance in all aspects will not be much lower than metal materials.

Metallic and non-metallic materials, under the premise of large-scale development of material technology, have gradually been blurred, the emergence of a large number of composite materials, to bring great changes to the world, steel-based materials, gradually replaced by plastics and other materials, plasticity is very strong, and there is a certain physical hardness of plastics, has become a universal material.

If there is now plastic, even the simplest plastic, the products produced by Ding Haijun, as well as the speed of development, will be several times more than now.

In the 21st century, almost in daily life, among the materials that come into contact, there are few that do not exist without plastic, and Zhao Xin also wants to make it out in this era, even if it is only embodied in the card system.

Plastic materials are not very heat-resistant and cannot be used in steam engines, but they can be used in other things, whether they are everyday products, or whatever.

Ding Haijun is poor and white, Zhao Xinxin has been working hard for the past few years, and it has developed very well until now, and if there are really few people at hand, what can be relied on is Niu Dali.

In order to get more new materials, Zhao Xin thought that most of the scientific giants in general are generalists, some mathematicians, and the level of physics, chemistry and other fields is also above the level, and some of them are special, and they can even create the honor of achieving great results in both industries.

Finding Niu Dali from the Daimyo's Mansion, Niu Dali proved himself with a series of examples, some flashes of inspiration, even Zhao Xin was impressed, he felt that Niu Dali may be a big fortune buried by history, and also tried to let him try to cross the line.

I haven't gotten out of the metal industry, just from ferroalloys, to other metal alloys, who knows, no, Niu Dali is on steel, there is a good inspiration, but other aspects are not good, not to mention a flash of inspiration, and it is very difficult to even stumble to complete a reaction.

This is something Zhao Xin didn't expect, after trying a few times, looking at Niu Dali at a loss, Zhao Xin was afraid that such a move would make Niu Dali completely lose confidence.

It's not that Zhao Xin is afraid of waste, among the new materials, any kind of discovery will create astronomical benefits, such a huge market in the Northern Song Dynasty can be used as a commodity too much, as long as it is worth the money, even ordinary researchers, Zhao Xin dares to come dozens or hundreds of times, Niu Dali's achievements, let alone such a point, even if it is tens of thousands, or even hundreds of thousands, it is not a problem.

Zhao Xin is still worried about Niu Dali himself, he is currently in the research field of Ding Haijun, the only person who can get his hands on it, even now, because the field of ferroalloy, many aspects, have reached a relatively deep level, Niu Dali's research speed is slowing down, but any research is not stagnant, it is advancing, but for various reasons, there is no breakthrough effect.

These projects are not all immediate interests, ordinary steel, has benefited the entire Northern Song Dynasty a lot, there is no need to rush to upgrade, those research projects, almost all of them are based on the future, in the future to obtain good benefits.

Of course Zhao Xin doesn't believe that Niu Dali can't cross the line, the reason why scientists have outstanding performance in many fields is that the key lies in his knowledge accumulation, as well as scientific thinking.

It's just that the well-known scientists of later generations first grew up in a learning environment, which is completely different from Niu Dali.

Niu Dali's family is poor, starting as an apprentice, although he is literate, he also revolves around his own name, as well as iron.

It can be said that from the beginning of his sensibility, all his life is iron, and his outstanding talent, coupled with his acquired efforts, makes him an excellent blacksmith, and his talent may only be a fraction of it, or even a tenth.

Until Zhao Xin, his own talent, accumulated knowledge, plus from all the blacksmiths, accumulated some secret recipes, so that Niu vigorously transformed, and then, according to Zhao Xin's guidance, carried out scientific research, analysis and summary, all kinds of scientific experimental methods, consolidated Niu Dali's foundation in the ferroalloy, under the strong foundation, that decay into a magical flash of inspiration, only to play a role.

2 years is too short, Niu Dali on the ferroalloy, the soaring colleagues, covered up his foundation, other fields, perhaps in the slow accumulation, after making up the basic knowledge, it is possible to develop, now, there is no such condition.

Niu Dali's current performance is not as good as that of an assistant researcher, which is completely different from the previous ferroalloy project.

Zhao Xin didn't dare to gamble, how long would Niu Dali be able to come out, time and cost were not a problem, in case Niu Dali lost his spirituality on the ferroalloy because of the blow, it would be worth the loss.

Without such a shortcut as Niu Dali, and without discouragement of Zhao Xin's enthusiasm, isn't it just training, starting from scratch, painting and calligraphy on a blank piece of paper, of course, it is easier than on a picture, anyway, except for alloys other than steel alloys, the others are all white paper, huge investment, no benefits, and it doesn't matter.

The material is like this, in the massive resources, the combination of exhaustive methods and summarization, plus a little luck, this is a long time ago all kinds of new materials in later generations, and now it is just a repetition of this process.

The continuous investment of the Dinghai Navy is willing to waste a lot of what can be done for the sake of certain results, and in the constant waste, these personnel who are directly thrown out almost grow up in such a destructive environment.

These simple education of Ding Haijun, or rather, they were scholars before, but they were more suitable for research, and they were all gathered together to study.

The textbooks for learning are, of course, middle school physics and chemistry provided by Zhao Xin, mainly the latter.

In the field of chemistry, middle school is only a beginning, and Zhao Xin only selectively indoctrins, so he learns even less.

A very large group of people simply mastered some basic characteristics, such as the position of the elements and the characteristics of the elements, and were thrown into the laboratory for experiments, which in the eyes of later generations is irresponsible, not to mention anything else, what to do if there is danger.

Even in a strict laboratory, no matter how strict the regulations, there will be some troubles, which are completely understood, and the materials used are not pure enough, and the danger is even greater.

Zhao Xin can't take care of it, danger, everything is dangerous, he can give them a good salary, he can give them a supreme status, but at least he must be worthy of him.

At first, it was just a verification, and Zhao Xin still remembered the things above chemistry in middle school, but some of the natural compounds obtained in nature were not pure enough, and they could not really be used.

But Zhao Xin didn't care, if the purity was not enough, he would purify it, let them verify those chemical formulas, and then look for experience and find suitable reactions.

Let a farmer who has just become literate go deep into the field of chemistry, and it is relatively easy to learn chemistry, because the reactions are visible to the naked eye, what particles react, and the reactions that cannot see the visible changes, these are not the things that are exposed to chemistry in middle school.

But even so, it is standing on the shoulders of giants, walking step by step, so that these people who are called semi-literate in the 21st century can directly intervene, isn't that destruction?

A bunch of things are taken together, and the steps of various experiments are carefully prepared, but the final things obtained are not the same, the effect of the reaction, and the final product are also very different.

In order to increase their efficiency, the person in charge of the laboratory will tell them the price of these products, which increases the psychological pressure.

Not everyone can be completely indifferent in the face of hundreds, thousands, or even counts, tens of times.

In middle school chemistry, reactions are all about something, for example, color change, for example, sound and light, such as heat and combustion, in short, they are all more violent reactions.

This kind of reaction is not calculated according to value, for example, using relatively cheap raw materials to produce relatively high-priced products, some reactions, even raw materials are relatively expensive, but the value of the product is low, it is only a process of verification and testing, not a method of industrial production.

For example, two 500 Wen products, through a series of reactions, cost 1500 Wen, and finally get a product that is everywhere in nature, and may only cost 100 Wen for a load.

Even if it is successful, it will cost most of the cost, not to mention the failure, looking at the piles of money, just like that, it becomes nothingness, and the requirements and mental pressure on the experimenter are huge.

This is to throw people out and beat them directly, violently ignoring everything else, and completely ignoring anyone's thoughts.

However, for Ding Haijun, it was the fastest growth process, just like in the War of Resistance Against Japan, why in the later period, the bigger the Chinese army, the better, the reason is very simple, China does not have sophisticated weapons, no perfect training, and no national defense system, so it can only rely on people.

A gun can send people to the battlefield, and after a battle, half of them are lost, and then they are replenished and sent again.

What kind of training efficiency is high, of course, it is biased towards actual combat, but no matter how much actual combat, it is not as good as real war, in countless wars, the veteran who has survived a hundred battles, perhaps in terms of technical actions and combat methods, is not as good as the elite of strict training, but why he can survive the rest of a hundred battles, is that he has his own unique skill, this unique skill, may not be suitable for large-scale training, but it is suitable for him.

China has infinite manpower to squander, and in the midst of huge sacrifices, all those who remain in the end are elites, and under the premise of auxiliary weapons and equipment that are not very different, of course they will win.

On the contrary, Japan, with its small territory and few resources, was the first batch and the second batch, the kind of soldiers who had undergone strict training, and after they were sacrificed, the remaining supplementary soldiers, their strength declined.

One side went up, the other side fell, and for a number of other reasons, in the end China won.

This is a last resort, and it is impossible for any ruler to do it blatantly, and there is no way to do it in that era.

This theory, Zhao Xin borrowed and used this process in the study of the Dinghai Navy, the difference is that this sacrifice is the material.

Ding Haijun had money and controlled the goods of the entire Northern Song Dynasty, plus the emergence of Dinghai coins, it can be said that as long as it is not an endless waste, this is completely affordable.

The insight of the later generations of travelers, as well as the card system, can make the material not deviate to the extent of looking for a needle in a haystack, and there is a certain direction, but for those who are completely unfamiliar and have just mastered the basic regulations, this is also a task that cannot be completed at all, such a task is not one or two, it is one by one, and it is overwhelmed.

In such a devastating research, most people can't stand it, hundreds, or even thousands of materials, just become waste in their hands, even if they don't have to bear the consequences, the pressure is huge, some people can't stand to quit, some people start to become mediocre, but under the big waves, there are still some people who stand up.

When this total amount reaches a certain level, the rest are elites, and these elites are what Zhao Xin really needs.
