"Hongfei, can you come to my house?" The elder said on the phone, his voice sounding a little excited, "I have good news for you." ”

"Okay, I'll be right over!" Hanging up the phone, Lin Hongfei's heart jumped "all ......": although it is not clear what good news it is, what can be called good news by the elder must be good news...... But what is the good news?

……………………

Before he arrived at the elder's house, Yang Taiping suddenly became nervous, "Boss, something is wrong." ”

"What's wrong?" Lin Hongfei looked around, everything was normal, there was nothing wrong.

"There are a lot of dark sentinels around, murderous...... It's heavy! As he spoke, Yang Taiping's tone had become extremely solemn, and the whole person was tense like a cheetah, as if it could pop out at any time, and at the same time reached out and opened the safety of the pistol on his waist.

"A lot of dark whistles?" Lin Hongfei frowned: Just when he entered the door of this community just now, the censorship seemed to be much stricter than usual, could it be ......, "Taiping, stop, I'll make a call first." ”

"It's good." Yang Taiping breathed a sigh of relief, the long-term and unremitting training over the years had given him a keen intuition, as if in the dark, there were several guns pointed at his car.

Lin Hongfei's car looks like an ordinary BMW. There is no difference between Chrysler 300C, but Yang Taiping knows that this is a bulletproof model specially customized by the company for Mr. Lin, which can not only prevent the close-range shooting of the Bayibar automatic rifle, but also the chassis can withstand the explosive power of 4 kg of TNT explosives, unless it is attacked with heavy machine guns, machine guns or high-power bombs, it is enough to ensure that the occupants of the car are safe and sound, but Rao is so. He is still a little nervous: there are no 12.7mm caliber heavy sniper rifles in China, and if special armor-piercing bullets are used, there is still no big problem in killing himself and Mr. Lin.

"Senior Elder, the strength of the guards below seems to have strengthened a lot?" Lin Hongfei touched the phone and called the senior elder, and asked with a smile, "What's the matter, I've never seen such a strong defense here." ”

In this compound live are experts from the Chinese Academy of Sciences and the Academy of Engineering, the top figures in the scientific field of the Republic, and the loss of any one person is a burden that the country cannot bear, and it is natural that there is a considerable military defense force. But it was so strong that Yang Taiping felt dangerous, that was another matter.

"Oh, you said this, I forgot to tell you, it has something to do with what I want to tell you." The elder suddenly realized. I was very embarrassed and apologized to Lin Hongfei again and again, "Do you want me to tell them." ”

"I don't think so." Lin Hongfei smiled bitterly. "I guess nine times out of ten, we're all being listened to right now."

"Hey!" Hearing this, the elder teacher was also happy, "Nacheng, if there is still someone listening on the other end of the phone, then pay attention to it, see if it scares our children...... All right. That's it, you hurry up. ”

As soon as Lin Hongfei hung up the phone here, Yang Taiping spoke again, "Mr. Lin." Gone is the feeling of being pointed at a gun. ”

Well? Lin Hongfei was stunned for a moment, and then shook his head helplessly: Nima! The phone of the emotional buddy was really tapped.

"So someone really tapped our phone?" Yang Taiping's face was ugly.

"It's not necessarily a wiretapping phone, there are actually many ways to eavesdrop, such as a long-distance eavesdropping method, by pointing a thing similar to an ultra-small satellite dish at our car, when we speak, the vibration of the car window glass is caused, this thing can accurately measure the vibration, and restore the content of our conversation." Lin Hongfei said, but seriously, whether his phone was really tapped or not, Lin Hongfei didn't have any bottom in his heart.

Yang Taiping didn't care so much, he didn't understand so much, as long as it wasn't his phone tapped, after thinking about it, he suddenly realized, "It sounds a bit similar to the way radar works." ”

"Well, almost." Lin Hongfei nodded, this description can't be wrong, is it finally his phone tapped...... Let's hope not.

…………………………………………

As a teacher, the place where he lives naturally cannot be shabby, this is a small two-story western-style building, and there is a lawn at the entrance of the yard that is not too small, which can be used as a temporary parking lot when necessary.

"Boss, go up, I don't understand what you say anyway, and I don't have to worry about your safety here, I'll be lazy and take a break in the car." Before Lin Hongfei could speak, Yang Taiping took the initiative to speak.

"Okay, if you're tired, you can sleep more, I don't think it will be over in two hours." Lin Hongfei did not refuse, he knew that Yang Taiping was taking the initiative to avoid suspicion, there are some words, it is one thing if you don't understand, but whether you can listen to it is another matter.

"I know it." Yang Taiping smiled honestly, "There is bread and water in the car, boss, you don't have to worry." ”

Lin Hongfei smiled and nodded.

This is the reason why Lin Hongfei is reluctant to change the driver, compared with other drivers, Yang Taiping is too sensible, and it is not easy to find such a sensible driver.

……………………

As soon as Lin Hongfei walked into the courtyard, he heard a hearty laugh from the house, the voice was very familiar, not only the voice of the elder, but also the voice of Huang Lao, the two of them seemed to have encountered something happy in the general task of Taishan Beidou in the field of materials of the republic, and they laughed very heartily.

"Senior, hello, Elder Huang, hello." Entering the door of the house, he quickly glanced at the people in the room, Lin Hongfei was like a primary school student who saw the school leader, "Hello Aunt Guo, hello Professor Zheng......"

"Okay, okay, don't be so polite," the elder waved his hand and said humorously, "It's all your own family, speaking of which, we old guys are still your subordinates, why are you so polite." ”

Lin Hongfei smiled, the elder can say so, but Lin Hongfei definitely didn't dare to think that these Taishan Beidou in the field of materials here were his "subordinates." ”

"You are an old man, why do you tease Xiao Lin every time he comes?" Ms. Guo Yunyi glanced at the elder fiercely, and said to Lin Hongfei with a smile on her face, "Xiaolin." You don't have to worry about them, these old men, the more they live, the more they go back. ”

"Confucius Ziyun: Seventy and do what you want, it is also an honor for a kid to make a few old men happy," Lin Hongfei said with a smile, not angry at all, "A few old men can make fun of me, and the 'reward' given is definitely not small." ”

"Old man, do you see it?" Old man Huang Peiyun pointed at Lin Hongfei and smiled, "This kid is very cunning." That's when we started planning to fight our autumn wind. ”

"What kind of autumn wind is this?" Compared with the lively and somewhat excessive old man Huang, the old man is a little more stable, but he is not stable, and he doesn't know what happened to Lu Dao, and he dances excitedly like a child. But in the next moment, Lin Hongfei understood why the two old men were so excited......

"Hongfei. Do you know the truth? We are on the basis of the third-generation single-crystal alloy that you got from Lao Maozi in Russia. Successfully manufactured the first batch of nickel-based single crystal superalloys estimated at 10 pieces. "The teacher's smile is as bright as a child, which is a kind of joy from the heart and flying away." Do you know the truth? The results of our testing are that the performance index of this batch of nickel-based high-temperature single crystal alloys is probably between the second-generation single crystal alloy and the third-generation single crystal alloy in the United States. ”

"What?!" The teacup that Lin Hongfei had just picked up in his hand immediately fell to the ground, and said in a trembling voice, "Senior Elder." Huang Lao, you're not making fun of the kid, are you? ”

Equivalent to the second-generation single-crystal superalloy and the third-generation single-crystal superalloy of the United States, Lin Hongfei is not the super rookie who didn't know anything about jet engines. has changed from a super rookie to a rookie, and knows how big the gap is between the second-generation single crystal alloy and the third-generation superalloy.

"What can we joke about?" The old man's eyes widened, and he was very dissatisfied with Lin Hongfei's suspicion of himself, but the next moment, he smiled, "Let me tell you kid, in this single crystal alloy, we have increased the content of refractory elements, especially rhenium, which has significantly improved the creep fracture strength of the blade, and the high-temperature creep performance is much stronger than the second-generation single crystal alloy led by PWA1484, CMSX-4 and Rene-N5 in the United States, well, it is about 20 degrees Celsius higher than the second-generation single crystal alloy of the Americans." ”

Speaking of this, the old man shook his head again and again with a regretful face, "Alas, it's still a little worse than the third-generation single-crystal superalloy that the Americans are working on." ”

Hearing the words of the elder, Lin Hongfei almost fell to the ground with his head!

The third-generation superalloys represented by CMSX-10 and Rene-N6 that the Americans are working on are only about 30 degrees Celsius higher than the second-generation single crystal alloys in terms of high-temperature creep performance, right? The "second-and-a-half-generation" you are engaged in is 10 degrees Celsius worse than the third-generation single-crystal superalloy that people are working on now, what is not satisfied?

That's right, this is only the first batch of "second-and-a-half-generation" single crystal alloys prepared under laboratory conditions, but in Lin Hongfei's opinion, this is the best beginning, can't wait, Lin Hongfei resisted the urge to grab the collar of the elder to pull the answer out of his stomach, and asked the elder, "Old man, how many years do you think it will take until we have large-scale industrial production?" ”

"If it's your company, it's about two or three years, and if it's handed over to the state to operate this project......" Senior and Huang Lao glanced at each other and shook their heads at the same time, "It's okay to say 10 years, and it's almost the same if it's 20 years." ”

Lin Hongfei thought deeply that with the country's efficiency and the style of state-owned enterprises, it was really okay to say 10 years or 20 years.

With his right hand slashed down, Lin Hongfei said, "It's produced in our company, this is our company's baby, who dares to rob Lao Tzu, see if Lao Tzu doesn't break his dog legs!" ”

These words were really vulgar, but when they heard Lin Hongfei's vulgar words, instead of getting angry, Elder Shi and Elder Huang shouted loudly, "Okay! With Xiaolin's words, our two old guys will be relieved. ”

After working in the system all their lives, Shi Lao and Huang Lao really know too well what the virtues of those state-owned enterprises are, especially now that the funds allocated by the state are insufficient and the funds allocated are seriously misappropriated, they can hear this sentence from Lin Hongfei's mouth, which is really the best news I heard today.

But the old man's stimulation of Lin Hongfei was obviously not over, he smiled and admired Lin Hongfei's expression of shock to the point that his jaw was about to fall, and continued to stimulate Lin Hongfei, "Boy, I know no, Old Man Huang has also made a breakthrough in the development of high-temperature turbines, and the old guy now has a new high-temperature turbine technology development route." ”

"Old fellow, are you giving me eye medicine?" Old man Huang scolded with a smile, turned his head and said to Lin Hongfei, "What the old man said is a bit excessive, but roughly there is an idea, Xiaolin, you know that I am engaged in powder metallurgy, and the turbine disc is also the most suitable for powder metallurgy to manufacture, my idea is to engage in AF115 + MER-76 two-component plus double heat treatment combination disc, in terms of mechanical alloying alloy, the use of less than 2% Y2O3 particle to strengthen the nickel alloy, so that the turbine disc can be set at 850 to 120 Du The performance of 1000 hours is better than the PWA1480 of the Americans, and the life of this single crystal blade made by the old man is increased by 2.3 times, the thrust-to-weight ratio of the engine is increased by 32% to 54%, and the temperature before the turbine can be increased to 1540~1650 °C. ”

"In addition, there is also an idea in master alloy smelting, argon atomization powdering, powder treatment, hot isostatic pressure forming, isothermal forging, heat treatment, ultrasonic inspection and surface strengthening, but these things are too cumbersome to say, so I won't go into detail one by one, if everything goes well, it should be almost possible to carry out industrial production at the same time as the blade of the old man."

Lin Hongfei seriously suspected that this was the old man Huang who was afraid that he would not understand and take care of his face, but it didn't matter, this was always a good heart, he thought about the progress of the project of the various models and models of turbines that the company was imitating, and couldn't help frowning: "Senior Senior, Huang Lao, can you first make a batch of blades and turbine disks with small batches of experimental values?" ”

"How?" Mr. Huang and Mr. Shi were a little strange, "This kind of laboratory product that has not been strictly verified is prone to problems." ”

"The company's engine is being manufactured," Lin Hongfei's expression was helpless, "I want to provide a small batch of engines for the manufacture of engines, and in addition, it can be regarded as testing these blades and turbine disks in practice, what do you two think?" (To be continued......)
