In the physics laboratory of the Tiangong Institute of New Materials, Donald, who was wearing a white coat, held the manuscript of "Development and Application of High-strength Titanium Alloys", one of the four papers handed over by Yang Weiping, how could he have the slightest shelf of a famous British authoritative professor of materials science, looking like an open-minded and studious student, tirelessly following Yang Weiping, who was doing tensile strength experiments, nagging, chattering and constantly putting forward some of his different views.

Titanium and titanium alloys, due to their high specific strength and good corrosion resistance, have been more and more widely used in aero engines and load-bearing structural materials.

As early as the early fifties, titanium was successfully applied to aircraft, although the amount of titanium used in each aircraft at that time accounted for only 1% of the structural mass of the aircraft, but it opened up a broad prospect of titanium application in the aerospace industry.

The first practical titanium alloy is the Ti-6Al-4V alloy successfully developed in the United States in 1954, because of its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility are good, and become the trump card alloy in the titanium alloy industry, the alloy has accounted for 75% ~ 85% of all titanium alloys. Many other titanium alloys can be seen as modifications of the Ti-6Al-4V alloy.

In the 50~60s of the 20th century, it was mainly the development of high-temperature titanium alloys for aero engines and structural titanium alloys for airframes, and a number of corrosion-resistant titanium alloys were developed in the 70s.

The high-strength titanium alloy proposed by Yang Weiping refers to the titanium alloy with a strength greater than 1100MPa at room temperature after heat treatment. In this paper, he pointed out that the tensile strength of titanium alloys strengthened by alloying alone is less than 1100MPa at room temperature, and if higher strength structural titanium alloys are required, titanium alloys that can be strengthened by heat treatment must be developed. By strengthening the titanium alloy by heat treatment, it is possible to increase the tensile strength to about 1500 MPa at room temperature while maintaining the desired plasticity.

This goal is a height that many materials science experts in various countries today dare not think of! It is important to know that the Ti-6Al-4V alloy, which is the most widely used in various countries, has a tensile strength of only about 900MPa at room temperature.

However, in this paper, Yang Weiping provides a possible basis and direction for the study of this goal.

The United States, the Soviet Union, the United Kingdom, France and other countries do not attach importance to the research of titanium alloys under the second-generation aluminum-lithium alloy. It is conceivable that once Yang Weiping's paper was published, it would definitely arouse the shock and doubts of those world-renowned materials science experts.

Academic papers are not scientific research results. Of course, Yang Weiping will not write about the preparation processes and methods of various mature high-strength titanium alloys in later generations, but only explain his personal views on the development and application of high-strength titanium alloys.

However, any science and technology begins with a possible theory and assumption.

Donald's argument for Yang Weiping, from the first questioning, arguing, to now humbly accepting, asking, just because Yang Weiping in the laboratory, in front of him, used model data to deduce the equivalent diagram of a high-strength titanium alloy, theoretically, the tensile strength of this titanium alloy at room temperature can reach 1241MPa under the premise of quenching + aging, and can reach 1162MPa in the case of annealing.

Although this is just a model, it makes Donald see that Yang Weiping's theory and assumptions are completely possible.

In fact, the Soviets have successfully developed a BT22 alloy in the laboratory in 1974, the strength limit of which can reach 1080MPa in the annealed and forged state, and 1370MPa in the intensified heat treatment state. It's just that Lao Maozi is still hiding BT22 now.

Therefore, Yang Weiping is not worried that once the paper is published, it will not be echoed by those who approve it. To put it bluntly, he just wants to use these four academic theories on different application fields to gild himself in the world's most authoritative journal "Nature".

Of course, another reason is that after the first aluminum alloy mountain bike is launched, those old bicycle manufacturers will definitely follow suit. Therefore, Yang Weiping must prepare for the upcoming business competition. …,

Launching one, preparing one, and researching another is the key to staying market-leading!

Besides, taking advantage of the presence of Donald, a famous British materials expert, to conduct in-depth exchanges and discussions on the research of titanium alloys with him, Yang Weiping will throw out a high-strength titanium alloy material in the future, which will no longer look so dazzling.

At that time, Donald will be pushed to the front, firstly, it can strengthen the British government's attention to him, and secondly, it can also form a hidden protective color for itself.

Singing a high note, sometimes you have to pay attention to the way and method. Many things have to be done in moderation, especially too much.

With Donald helping to take the paper to the journal "Nature" for submission, Yang Weiping basically didn't have to worry about it anymore.

On the fourth day after the rotation training team of Panshi Security Company left Hong Kong, Yang Weiping received a call from Hughes Field in the laboratory, reporting to him that the assembly line of the first Giant mountain bike had been fully installed and commissioned, and asked him to hold a celebration of the first mountain bike off the assembly line on January 20, which will be after 9 o'clock tomorrow morning.

Yang Weiping has never liked to participate in such public events, but he couldn't resist Hughes Field's kind invitation, so he could only agree.

Doing experiments in the laboratory, time seems to pass very quickly. If it weren't for Qiu Fang coming over with a lunch box to deliver food, Yang Weiping, who had been busy with the metallographic structure analysis of high-strength titanium alloys, would have found that he was so busy that he even forgot to eat dinner.

This chemistry laboratory is Yang Weiping's private laboratory, and there are two security guards guarding the door 24 hours a day. Except for Qiu Fang and Xiang Rong, no one was allowed to enter this laboratory without Yang Weiping's permission. Because this time, Donald and his four assistants said that he was stingy in front of Yang Weiping.

Qiu Fang wore a dark green velvet cheongsam today, and a beige woven flower buttonless vest was put on her coat, which highlighted her tall and plump figure to look curvy, and her black and shiny hair was wrapped in a black silk mesh with a lady's bun hanging down her head, a pair of drop-shaped green jade pendant earrings lined with white and tender earlobes, and a pearl necklace tied around her snow-white jade neck, adding a few elegant luxury.

With her willow-like waist and round and straight plump buttocks gently twisting, the black and delicate high-heeled leather shoes stepped on a straight line, and a pair of jade legs appeared and disappeared from time to time on both sides of the cheongsam over the knee.

"You, every time you get busy, you forget to eat. Qiu Fang came to Yang Weiping's experimental table, and while serving out the hot meals and hot dishes in the food box, she said with concern: "In the long run, even if you have an iron stomach, you will have to fall ill." ”

"Sister Fang, here. Yang Weiping still maintained the posture of looking at the microscope lens, and greeted Qiu Fang without raising his head, "I'll be done soon, wait a while." ”

Watching him observe in front of the microscope while holding a pen to record the data, he was so attentive and engaged that he didn't notice that she was dressed up today, and the idea of giving him a surprise was also in vain. Qiu Fang couldn't help but glance at him faintly, stood quietly beside him, and looked at him silently, unconsciously a little stunned.

Since the last time she let him hug, the relationship between her and him has become much closer than before, and every time she gets along with him alone, she is no longer as cold and indifferent as when there are outsiders, and her expression and tone will always inadvertently reveal a faint intimacy and love.

Maybe it's the reason why she connived at him, this enemy is getting more and more bold towards her, and wants to kiss her on the mouth when he hugs her several times, of course she won't let him succeed, but his face is not less stained with his saliva.

After finishing the last set of data records, Yang Weiping was just about to straighten his waist and raise his head, but out of the corner of his eye, he suddenly found Qiu Fang looking at him in a daze, and couldn't help but move in his heart, while pretending to continue the experiment, he secretly glanced at her. …,

It didn't matter what he saw, and he was stunned for a moment.

It's so beautiful! Sister Fang's dress today is so beautiful and seductive!

Of course, Yang Weiping is no stranger to the cheongsam she wears, as well as the jewelry she wears, which he personally bought for him, but she has never worn it or worn it.

What day is it?Why is Sister Fang dressed up so beautifully?

Yang Weiping couldn't help but think about it in his mind, but after thinking about it, he didn't think that there was anything special about today's day, January 19th, a very ordinary day!

Hehe, she's in a daze at her brother again! It seems that this guy Hughes Field is right, in fact, the buddy is still a bit of a man, but we haven't found it before.

Qiu Fang not only wore a cheongsam and jewelry today, but also lightly applied fat powder to that pretty face.

Seeing her diamond-shaped mouth with a light layer of lipstick, Yang Weiping felt an urge to rush over and bite twice.

As soon as this thought was born, Yang Weiping immediately found that the little brother between his legs immediately looked up and set up a tent between his trousers.

Damn! She can't find out.

Yang Weiping subconsciously bowed his waist in order to make his crotch looser.

Qiu Fang saw Yang Weiping's body move, and then realized that this enemy was tilting his head and staring at her at some point.

"Look at what, don't hurry up and wash your hands and eat. Qiu Fangqiao's face flushed, and her apricot eyes widened and glared at him.

"Hehe, Sister Fang, you are wearing this today, it is so beautiful and charming. Yang Weiping smiled and rubbed his hands together and circled around Qiu Fang.

Seeing his two eyes turning back and forth between her chest and waist and thighs very dishonestly, Qiu Fang couldn't help but be a little flustered, her face turned red, and she said angrily: "What do you want to do?" ”

"It's beautiful and delicious, the ancients are honest and don't deceive me!" Yang Weiping praised sincerely: "Sister Fang, do you know how many men you will charm when you dress up like this!"
