"Failed. ”

Mu Jingchi sighed, this was not unexpected, after all, this was the first time that he really did a complete experiment, from beginning to end from the design of the experimental scheme to the construction of the theoretical structure, and then to the hands-on practical experiment.

"However, I was too quick to get into trouble!"

It is normal for experiments to fail, there are too many factors that affect materials in materials research, and many of them are at the atomic level, and it is impossible to manipulate atoms at all.

In addition, Mu Jingchi is also the first time to get started with the material process, and the existence of some errors can lead to a wide variety of material properties.

"The crystallization process of the ingot failed. ”

After the metal material is smelted, it is cast into an ingot mold or casting mold, and through cooling, the liquid metal is transformed into a solid metal to obtain an ingot or casting of a certain shape.

This process is a crystallization process.

The ingot is polished with metallographic sandpaper and then eroded with an erosion agent. When viewed under a metallographic microscope, the microscopic composition of the interior can be seen.

These wholes, which are made up of one or more phases that differ in morphology, size, and distribution, as well as various material defects and damages, are tissues.

It's just that the phase in this is very different from the phase diagram simulated by Mu Jingchi, and the defects and damage of the material are very obvious.

As soon as I tested it, I knew that the performance of this material was not good at all.

There is no need to go through the subsequent molding and recrystallization, and the material fails in the first crystallization process.

Although he failed, Mu Jingchi was not discouraged, after all, failure is the mother of success.

On the contrary, he was very interested, finding out all the data obtained from the experiment, using mathematical and physical knowledge to analyze it, and conducting more detailed research on materials engineering processes.

The second time, failed.

The third time, failed.

Fourth, failure.

For the fifth time...

As the number of failures increases, Mu Jingchi becomes more and more proficient, and he is more and more in-depth for various data, and he can instantly know whether the data is normal when he looks at a set of data. If it is not normal, which link is the problem, and how should it be improved?

At this time, Mu Jingchi is deeply grateful for the knowledge in "Fundamentals of Materials Science (2069 Edition)". For materials researchers fifty years from now, that's the foundation.

But for the current Mu Jingchi, a lot of it is advanced knowledge.

Using this knowledge, Mu Jingchi's understanding of materials is more comprehensive, more in-depth, and more sensitive to data. With the help of this knowledge, he already feels that he is not far from success.

Experiments are a time-consuming thing, and Mu Jingchi, who is immersed in the experiment, doesn't care about the passage of time at all.

In the blink of an eye, it was already the end of December.

According to the solar calendar, the New Year's Eve will be in two days. Of course, there is no vacation for graduate students, and generally winter and summer vacations are a week's rest, which is considered a vacation.

this day.

Professor Yang came to this floor of Mu Jingchi's experiment and entered the graduate student's office. At this time, Mu Jingchi was calculating and correcting some data, striving to obtain better performance materials in the next experiment.

"Professor. ”

Unlike many graduate students who call their supervisors bosses, Mu Jingchi has always called professors directly, and he doesn't like the title of boss.

In addition, it is generally called a boss if it is a research of a commercial nature. The projects undertaken by Professor Yang are basically national projects, which are funded by the state for research and development, and work with other research institutes to complete the research and development of national projects.

So the boss is really not suitable for Professor Yang.

Yang Wenwu raised his hand and asked Mu Jingchi to follow him out of the office, this is not a place to talk, after all, there are other graduate students studying.

Come outside, stand in the hallway, and look at the scenery outside.

"How is it, do you have any regrets?" Yang Wenwu asked Mu Jingchi, with a smile on his face, "I heard that the results of your own experiments are not ideal?"

Mu Jingchi also laughed, he smiled from the heart, after all, Professor Yang's actions proved that he still cared about him.

"It's okay, although the results of the experiment are not ideal, but they have been improving. ”

"It's a bit boring to work on materials, isn't it?"

Mu Jingchi nodded, and shook his head again, "It's really boring, but I'm used to it." However, I didn't find it boring, it was quite interesting. ”

Compared with the outside world, it is not easy to engage in material research.

In his previous life, he experienced the world of the Internet, and all kinds of interesting and interesting things were displayed in his life. In this life, the life he has experienced is a school laboratory and a home cottage, which can be described as a real two points and one line.

He didn't even have the heart to read the comments on "Luzhou Month" in Netease Cloud Music, which shows that he is busy and boring.

However, Mu Jingchi likes the current state very much. The world is always diverse and ever-changing, and it can be described as colorful, but this kind of two-point and one-line life is also what he likes.

Enjoy the richness of knowledge that comes with experimentation, and the sense of peace and quiet that comes with the house and the system.

There is a sense of minimalist living.

Professor Yang's smile became even brighter, and he patted Mu Jingchi on the shoulder like his own relatives and elders, "You are very good, very stable, and you are really suitable for materials." ”

Many students are talented, but they can't hold back the impetuosity in their hearts, are blinded by short-term interests from the outside, and end up wasting their talents.

But Mu Jingchi's steady mentality is very much liked by him.

Now that the country's economy is up, it is not as embarrassed as before, and the investment in material research can be said to be a sparing investment, and the treatment of scientific researchers will only get better and better.

"Do a good job and don't be discouraged. In materials research, experimental failures are a common thing, and it's good to look away. ”

Mu Jingchi nodded, "Got it, Professor." ”

Yang Wenwu walked again with his steps, and Mu Jingchi returned to his office to continue studying the data.

···

Park the car and take the elevator home.

The elevator stopped on the first floor, and a girl walked in with a big suitcase, which made Mu Jingchi look twice.

Because the area of this building is limited, there are not as many residents as other buildings, and getting up early every morning to see and listen more almost let Mu Jingchi know the residents of this building.

But he hadn't seen the girl.

The girl's body is not tall, less than Mu Jingchi's shoulders, about to her chest, and she has short hair. She was about to press the floor of the elevator, and when she saw that the floor showed 27, it was the floor of her house.

couldn't help but look at Mu Jingchi twice.

Mu Jingchi was not shy, the girl looked at him, and he also looked straight at the past.
