Siheyuan, the opening gun is aimed at Yi Zhonghai

The journey back to the old city was not as hurried as the trip there.

Zhou Zheng drove the car, stopping and starting along the way, enjoying the scenery along the way, and they did not return to school until five days after the start of the school term.

After returning to school, Zhou Zheng secretly gave some gifts to his class teacher.

With the help of the class teacher, Tian Xinyue and He Yushui did not have to choose to be demoted.

Of course, even if you don’t get demoted, you still have to take the necessary exams.

Fortunately, the teacher gave them seven days to review, and Zhou Zheng took advantage of this time to review the courses he had learned in his freshman year and taught them to Tian Xinyue and He Yushui.

Zhou Zheng's teaching level is absolutely top-notch. After all, with the experience of hosting the "primary school" as a foundation, he quickly figured things out.

Tian Xinyue and He Yushui both have good learning abilities. They can remember everything Zhou Zheng explains once.

However, time was running out, with only six days left before the exam. Zhou Zheng had to learn so many knowledge points, which made him worry about whether he could complete the task on time.

So, he entered the points mall without hesitation, exchanged 300 points for two [Enlightenment Pills], and gave one to Tian Xinyue and He Yushui each.

[Enlightenment Pill]: Can temporarily increase thinking activity for up to 12 hours!

Sure enough, with the blessing of [Enlightenment Pill], Tian Xinyue and He Yushui's learning speed soared instantly.

Not only can they quickly remember the knowledge Zhou Zheng explained, but they can also integrate this knowledge and put forward their own unique insights.

This change makes them feel extremely excited and happy.

However, after a series of verifications, they were surprised to find that the [Enlightenment Pill] actually had considerable side effects.

It turns out that the brain needs to consume the sugar in the body as a source of energy when working, and the effect of [Enlightenment Pill] is to significantly increase the activity of the brain, causing the brain's demand for sugar to increase exponentially when working.

Therefore, Tian Xinyue and He Yushui had to consume a large amount of glucose every day to maintain the normal functioning of their bodies.

Despite this, the two insisted on taking the pills.

After all, learning outcomes are visible to the naked eye.

Soon it was time for the test and the head teacher brought the make-up exam papers for the science class.

When they saw the test paper, Tian Xinyue and He Yushui were full of confidence because they had already grasped all the knowledge points firmly in their minds.

Sure enough, they finally passed the supplementary exam with excellent scores of almost full marks, which shocked the class teacher, who thought they were all gifted geniuses.

For such students, of course, special educational methods must be adopted.

Coincidentally, the head teacher happened to be recruiting people for a research project.

So, he invited Tian Xinyue, He Yushui and Zhou Zheng to join the research team without hesitation.

In this way, the three of them began an academic journey full of challenges and fun.

This research topic belongs to molecular materials science, and the research and development direction is heat-resistant metals.

The specific function is unknown, but the requirement is a material that can withstand temperatures of 3700 degrees.

You should know that tungsten, the most heat-resistant metal in the world, can withstand a maximum temperature of 3410 degrees. If the temperature exceeds this, tungsten will melt, so it is much more difficult than imagined to make improvements in this regard.

In addition, the material cannot be tungsten alone, because tungsten alone is too brittle to be used as a structural material. Other elements need to be added to improve its toughness and strength.

This greatly increases the difficulty of the experiment.

However, this is just a research direction and it has little to do with whether or not results can be produced.

In fact, in this era, the country's scientific research institutions have many such projects, most of which are brave attempts.

For college students, these projects can help them accumulate experience, learn new knowledge, and develop problem-solving skills.

For the country, this is also an investment in the future development of science and technology. Even if it may seem to have no practical application value now, who can guarantee that there will not be new breakthroughs in the future?

Zhou Zheng, Tian Xinyue and He Yushui did not reject their mentor's proposal and successfully joined the project team.

It is also from this time that they have to not only complete the required subjects, but also choose to take some materials science courses.

In such a tense and busy atmosphere, time passed quickly like water released from a floodgate, and two years had passed in the blink of an eye.

From the initial 1900 degrees to the later 2600 degrees, 2900 degrees, 3100 degrees...

As time went by, the project team's progress was slow but orderly.

Of course, Zhou Zheng actually had a better solution in mind, but he did not make it public.

Because after careful consideration, he believed that scientific research should focus on the process rather than the final results. If the finished product is produced too early, it will fall into the situation of losing sight of the forest for the trees.

So during this period, he did not reveal his thoughts to anyone.

Over the past two years, Zhou Zheng has been committed to the research of high-temperature resistant materials and has made remarkable progress.

However, he had no idea of ​​what the project would actually be used for.

Out of curiosity, he once tentatively asked his supervisor: "What is the role of this heat-resistant alloy we are studying?"

But the instructor remained tight-lipped about the issue and only told him that this was a confidential project.

Zhou Zheng secretly speculated that such highly heat-resistant alloys should be used in some special fields, such as the construction of nuclear reactors, or the aerospace and chemical industries.

Because under normal circumstances, there is no need to use such a high-temperature resistant alloy.

You should know that the highest temperature a material can withstand is not equivalent to its actual upper temperature limit.

Take pure tungsten for example, its actual operating temperature usually does not exceed 3100 degrees Celsius.

After some thought, the experiment finally locked on the option of tungsten-rhenium alloy.

Compared with pure tungsten, tungsten-rhenium alloy has better mechanical properties, ductility, processability and weldability.

The so-called tungsten-rhenium alloy is an alloy made by mixing the two metals tungsten and rhenium.

It is precisely because of the addition of rhenium that the overall performance of the alloy has been greatly improved.

Compared with pure tungsten, tungsten-rhenium alloys show outstanding advantages in both mechanical properties and ductility.

However, at this time, my country's understanding of the element "rhenium" is still in its infancy, and it can be said that we only have a superficial understanding of it.

The successful development of tungsten-rhenium alloy is full of accidents, and the data of this success does not mean that it has become a mature technology.

Furthermore, obtaining rhenium is itself extremely challenging.

The rhenium we used was obtained from laboratory samples, and the remaining amount was not enough to carry out another successful experiment.

In fact, foreign research on tungsten-rhenium alloys has been successful and is expected to be put into practical use within the next two years.

Faced with this situation, we must gradually carry out experiments to break the foreign technological blockade.

When the maximum operating temperature of the alloy material reached 3100 degrees, the instructor reported the project to the Academy of Sciences because the university's project team could no longer afford the subsequent experimental costs.

Although 3100 degrees did not break the target of 3700 degrees, the significance of this achievement is far more insignificant than it seems.

In fact, there are less than a handful of countries in the world that can produce materials with a maximum operating temperature of 3100 degrees. Such an achievement is enough to change history.

Zhou Zheng's plan was actually obtained through the [Knowledge Cards of Other People's Children], but he was sure that this plan would definitely achieve the goal of 3700 degrees, or even far exceed this goal.

However, the materials involved in this plan were not universal, and were not possessed by any country at the time.

What’s worse is that even Zhou Zheng himself doesn’t know the specific name of this material. It only has a code name in the points mall, KPL_.

As for the price, it is as high as points per gram! This is also one of the specific reasons why Zhou Zheng did not propose this plan.
