"Chromium improves the stability of supercooled austenites in the transition zone of 600 to 650 degrees Celsius, especially at low temperatures of 300 to 400 degrees Celsius, so that the gestation period increases and the curve shifts to the right. At the same time, I observed that as the chromium content increased, the pearlite transition partly shifted to high temperatures, the bainite transition partly moved to low temperatures, and the two parts gradually separated, presenting two 'noses', with austenite appearing at 350 to 450 degrees Celsius having the highest stability......"

Zhao Qingshan's 945 test steel chromium element stage data is ideal, and he shared the data with his colleagues.

As far as HSLA such as 945 steel is concerned, the position of C element is as important as ever, and various alloying elements have carbonization with C element, and there is also interaction between alloying elements.

"Xiao Zhao, your speed is really fast, and the result is very good. Liang Minfang gave a positive evaluation, and the alloy elements she was responsible for did not perform very well.

"Sister Liang, show me your data. ”

"Give. ”

Everyone works in the same laboratory, using the same series of dilatometers, hardness testers, and microscopes, and colleagues work together, supervise each other, share information, and work together.

Zhao Qingshan carefully looked at Liang Minfang's test sheet and said: "Manganese lowers the Ar1 temperature of steel and shifts the curve to the right. ”

Liang Minfang nodded and said: "Yes, I want to try it on the next few furnaces of test steel, with the increase of manganese content, is the normalized of low carbon steel prone to bainite structure?"

"I think it's possible, give it a try. ”

Zhao Qingshan left the trial production workshop and rode home.

The dedication to work makes people forget the days, today is Sunday, the only day off of the week.

The cold winter has passed, the early spring is coming, the temperature is not high, but it is enough to support a variety of outdoor activities, the cat is active for a winter, there are no tourist attractions in the industrial area of the steel city, the workers and their families entertain themselves, take local materials, but also happy.

Outside the 12th neighborhood unit building, Meng Xiaoqing, a senior high school student, squatted on the ground and played with his friends.

The entertainment is "skimming", which is a triangular combat tool made of cigarette box paper, which is also a bargaining chip.

Pia！Pia！

The sound of playing "skimming" is endless, Meng Xiaoqing is good at this, he started with three swimming "skimming", and soon won back Hongtashan "skimming" and 555 "skimming".

In the underground trading system of contemporary primary and secondary school students, five swimming "skimming" is exchanged for one Hongta Mountain "skimming", and three Hongta Mountains are exchanged for one 555.

The main group of people who play "skimming" is primary school students, and Meng Xiaoqing, a senior high school student, plays against primary school students, and primary school students are certainly not his opponents.

"Ahh

"Brother, don't go, I'll pick up cigarette paper!"

The elementary school students who lost all their money were not discouraged, but became more and more courageous, and they would never give up until they defeated the boss of the third year of high school.

Meng Xiaoqing, who had a bumper harvest, said tastelessly: "You are too weak, boring, I don't want to play with you, scatter, go home and do your homework." ”

Meng Xiaoqing immediately returned all the spoils to the elementary school students in the neighborhood, and even his capital --- three swimming "skimming", and he also lost it.

Syllable!

A slap slap on the back of Meng Xiaoqing's head.

The person who slapped was Zhao Qingshan: "Meng Xiaoqing, how boring are you, even a primary school student is a liar?"

"I didn't lie, I won with my ability!" Meng Xiaoqing argued with reason, and said: "Brother Xiaoshan, I've been waiting for you for a long time, today is Sunday, you haven't rested, have you gone to the unit?"

"Yes, I just came back from the unit, what are you waiting for me?"

"I was first in my class in English. ”

"So Xiaoqing, you are waiting for me to report the good news?"

"That's right. ”

"You got the first place in English, what is your score?"

"One hundred. ”

"Full marks, amazing, congratulations. What about physics and chemistry, what about the other subjects, and what is the overall score?"

"Physics and chemistry have also improved, but not as fast as English. The total score is 378. ”

"Dinner at your house on New Year's Day, you scored 302 points, in less than two months, you improved by more than 70 points, Meng Xiaoqing, your head is smart, and your IQ exceeds the average. There are still more than four months to go to the college entrance examination, to maintain this momentum, Xiaoqing, the choice you face is not undergraduate, junior college, but which key university to fill in. ”

"This is thanks to Brother Xiaoshan's guidance to me, you teach better than our teacher. ”

"You can't say that, without the foundation laid by the teacher, I can't elevate you. For example, in mathematics, I don't want to care about you, you can work your own and try to get a few more points in mathematics. Seriously, with a perfect score of 12 in mathematics, even if you only get half of the score in the college entrance examination, 60 points, then you will go to Tsinghua University. ”

"Tsinghua...... I didn't dare to think about it! Brother Xiaoshan, there is something I want to tell you, my English test has a perfect score at once, not only the first in the class, but also the first in the whole grade, and the English teacher is a little suspicious of me. ”

"Xiaoqing, your English is not bad in the first place, and through your unremitting efforts, it is understandable that you suddenly erupted. What's more, if you get a full score in the exam, if you want to copy, someone else will copy you, and you don't have the possibility of plagiarism. The English teacher suspects you, not because he suspects you of cheating, but because he wonders the real reason for your sudden outburst?"

"Yes, yes, yes! Brother Xiaoshan is strategizing, winning thousands of miles away, you don't know our English teacher, and he actually analyzed his mentality so thoroughly. ”

"You showed your teacher those English hand-copied review materials I gave you?"

"No, no, no, but I showed it to a few classmates who had a good relationship...... Brother Xiaoshan, don't be in a hurry to hit me, I just let my classmates take a look!"

"And then?"

Then my classmates came to me to ask me about English. ”

"You're the first in your grade in English, so it's okay for you to guide your classmates. Again, I stress that you are only allowed to study at home and not to take all kinds of handwritten materials that I have given you. ”

"I didn't take it to school, last Sunday, my dad and mom went to the morning shift...... On Sundays, they also have to work overtime to catch up with production, and Jianggang is too busy now. My parents went overtime, my sister took turns off that day, she went out to play, I was alone at home during the day, and several classmates who had a good relationship came to my house to study together, and the review materials you gave me were inadvertently glanced at by my classmates, and then I put them away. ”

"So what?"

"So my classmates felt that there must be a mysterious master behind me who was tutoring me. ”

"And then you betrayed me?"

Even if I, Meng Xiaoqing, die, I will never reveal half a word. ”

"Let me summarize, Meng Xiaoqing, you have been waiting for me at the door of the unit building all morning, one of which is to inform me of your remarkable progress in academic performance. I am happy and relieved about this. Second, you have made some mistakes in confidentiality, but they have been remedied through timely and effective means. In this regard, I hope that you will continue to strengthen your sense of confidentiality. You see, I'm not an all-powerful savior, I have limited energy, and I can only save you alone. ”

"But Brother Xiaoshan, it turns out that the review materials you wrote are much better than the college entrance examination review materials of the Chuzhou Education Publishing House, you don't need to be so low-key, you can publish it." ”

"Meng Xiaoqing, you know a fart. ”
