v2 Chapter 264： Mu Yang draws pie again
As the Chinese New Year is approaching, more and more migrant workers are returning home for the New Year.
Some migrant workers, when talking on the phone with their family members, probably know about the development of the family, they already know about the Youth Reservoir and the Food Street, and they come back to have a look.
But some migrant workers, who are usually so busy and don’t have a lot of phone calls at home, can’t understand the changes in their hometowns. When they pass by the food street in the car home, they suddenly find:
When is there a food street in town?
When did Young Reservoir become so impressive?
wow!
What a big change!
The terrain of Lujing Town is flat, with mountains but not high, and it is like spring all year round. Even if there is no Xinghai Food Street in the town, there are still many roadside stalls and food stalls in the town, but they are not as large and unique. Everyone likes to come to this area, and it can also attract diners from farther areas. attracted.
The parking lot in front of the restaurant is about 60 to 70 meters wide and several hundred meters long. It is trivial to park thousands of cars in such a large open space. Nowadays, there are not many people with cars, and most of the villagers travel on battery cars. Tonight, there are still two or three hundred cars parked. Many of these diners come from the city or the county.
Especially at seven or eight o'clock at night, the food street is brightly lit, and each restaurant is covered with a coat inlaid with night pearls. If you look at it from the sky, this food street looks like a shining galaxy.
Diners and tourists were chatting and laughing, and they were also surprised by the beautiful night view and lively scene of the food street. Some diners were bored to observe, and it turned out that the food street gathered at least 3,000 people!
The food street is very popular and has become a leisure center and food center for the villagers in the town.
Mu Yang had nothing to do at night, so he accompanied Song Xuelu to the food street for a walk.
After walking around with Song Xuelu for a long time, they were quickly recognized!
"Boss Mu is here!"
"Wow, Mr. Mu is here! Hello, hello!"
"Everyone, come and see, the big boss is here to go shopping!" Especially the children, exclaimed and screamed, as if they had discovered something new: Wow, come and see, there is a monster here!
Mu Yang felt strange when he heard a child shouting, so he shouted, but don't shout "Everyone come and see", it was not lively enough.
Some wage earners had never seen Mu Yang in person, but when they saw the excitement ahead, they heard that Mu Yang was here, so they walked over to take a look.
Mu Yang and Song Xuelu were recognized, so they had to greet everyone enthusiastically.
"Hello, my fellow villagers, don't be so enthusiastic." Mu Yang waved his hand and smiled, feeling a little bitter in his heart.
However, there were more and more people around, and thirty or forty people gathered in less than a few minutes. Mu Yang knew that he couldn't continue shopping, so he had to say: "Thank you for visiting the food street, if you have good suggestions, you can ask The staff brought it up.
I will increase investment in my hometown. At present, the salary may not be as good as that of big companies in first-tier cities, but it is definitely much better than that of factories in Guangdong and Dongguan. At the same time, I hope that young people will join in the construction of their hometown. I believe that our Lujing Town will be better and better, and everyone's income will be higher and higher. I believe that in a few years, every family will have a car and can live in a better place building. "
Mu Yang is not bragging, even without him, ten years later, not to mention that every household has a car, one-third of the family has a car is really not a problem.
"Mr. Mu said it well!"
"Thank you Boss Mu, with the support of the big boss, the development of my hometown will be faster!"
Now everyone knows that Muyang distributed red envelopes to the elderly in his village, and threw 6 million yuan all at once. Muyang has donated to the primary school in their village, the village road, and the middle school in the town, and they are sincerely doing charity.
Moreover, the salaries of food companies and cultural tourism companies are indeed very good, and many young people who work outside want to come back to work.
Mu Yang chatted with the villagers for a while, drew a few big cakes, and said a lot about imagining a better future life, and then took Song Xuelu away.
Tonight, he is going to take Song Xuelu home.
Well, the two of them haven't been in bed for several days, and they're really not used to it, especially this cold night, it's the most suitable.
At eleven o'clock in the evening, the two finished a set of radio gymnastics created by themselves. Mu Yang was a little tired and lay on the bed like a "tai", while Song Xuelu hugged Mu like a gentle kitten. Yang falls asleep.
Afterwards, Mu Yang's favorite thing to do is to be able to calm down and think about something.
He is planning the development of the material.
The titanium alloy workshop has been put into production. After the year, Junfang will order specific specifications of plates or profiles to truly enter mass production;
The aluminum alloy plant is currently under construction and will be operational around April.
It is impossible for an aluminum plant to produce only two models of materials, and Muyang needs to add more models. Some materials cannot be researched by the current R&D team.
At present, the aluminum alloys 6009 and 6010 researched and produced by Xinghai Group belong to the automotive sheet.
In addition to aluminum alloy automotive plates, domestic aluminum alloy materials, especially high-strength aluminum alloys, are also in a blank area.
The tensile strength of 6009 and 6010 is not high, and the strength is about 320mpa and 360mpa respectively, which are not high-strength aluminum alloys.
But they have the advantage that they have good plasticity and can make structures of complex shapes, so they are very good for complex structures such as four doors and two covers of automobiles.
For some structures that require high strength, high-strength aluminum alloys are required, and aluminum alloys 6009 and 6010 are not suitable.
High-strength aluminum alloys refer to aluminum alloys whose tensile strength is greater than 480mpa, mainly 2 series (hard aluminum alloys) and 7 series (superhard aluminum alloys) series alloys.
Due to the chemical composition of the alloy, the way of melting and solidification, the processing technology and the heat treatment process, the properties of the alloy vary greatly.
Take the 7090 series with the highest strength among the current aluminum alloys. For example, the highest tensile strength of the m7090 aluminum alloy in the beautiful country is 855mpa, the tensile strength of the en aluminum alloy is 840mpa, and the tensile strength of the aluminum alloy in the island country reaches 900mpa. The tensile strength of ultra-high-strength aluminum alloy is only 740mpa.
From the numerical point of view, even if it is the same type of material, the tensile strength is so different!
900-740=160mpa!
For materials, there is a difference of two grades.
Most of these high-strength aluminum alloys are used in aviation. For example, for structures of the same strength, one only needs 740kg, and the other needs 900kg (equivalent to thickening), which is equivalent to 160kg heavier.
Therefore, my country still relies on imports for high-strength aluminum alloys.
Mu Yang plans to add another aluminum alloy material, namely high-strength aluminum alloy, while he has nothing to do at home, and organize the information in his mind first. It is estimated that the supercomputer and the human brain information converter will be available in March or April.
Of course, it does not mean that high-strength aluminum alloys can be used in components that require high-strength, completely replacing high-strength steel and titanium alloys.
Aluminum alloy has a fatal weakness, that is, the melting point is too low!
470-650℃!
In the field of materials, there is a term called "high temperature creep resistance". Simply put, the higher the temperature, the softer the metal material will become as it approaches the melting point, and its strength will become weaker.
Therefore, the actual temperature range of aluminum alloy is below 150 °C, and its performance drops sharply if the working conditions exceed this temperature.
Of course, his advantages are low density, low price compared to titanium alloys, high output, easier processing and welding.
According to the advantages and disadvantages of titanium alloy and super aluminum alloy, it is reasonably arranged on the aviation plane.
For example, when the aircraft is flying at high altitude, the pressurized cockpit of the fuselage is under internal pressure, and it is necessary to use duralumin with high tensile strength and fatigue resistance as the skin material.
The fuselage frame is generally made of 7-series super-duralumin, and the reinforcement frame that bears a larger load is made of high-strength structural steel or titanium alloy.
For example, parts that require high temperature resistance and strength, such as aircraft engines, bulletproof parts, reinforced parts, reinforced parts, combustion chambers, turbine shafts, turbine disks, nozzles, etc., are mostly made of titanium alloy materials, and aluminum alloys must not be used. .
Judging from the current consumption of aviation aircraft, aluminum alloy materials account for about 50% - 70% of the total metal materials used in aircraft (civil aircraft); if the requirements are higher, then increase the proportion of titanium alloys.
Muyang has mastered the production of titanium alloy tc4, ta7, and super-strong aluminum alloy, and can basically produce and manufacture the main materials of aviation by himself, so that he has a certain foundation, does not depend on others, and will not be stuck by foreigners.
Of course, the key materials for aircraft include superalloys, ultra-high-strength steels, and composite materials.
On the road of aviation materials, Muyang still has a long way to go, but he has already taken the first step.
After thinking about this, Mu Yang did not hesitate to search for high-strength aluminum alloys in the achievement point store.
Soon, Mu Yang found the material technology he wanted.
"Manufacturing process and formula of a new type of aluminum alloy 7090"
[Introduction: A new alloy formula, using new melting and solidification methods, processing technology and heat treatment technology... The tensile strength can reach up to 960mpa, and the plasticity can reach 12%...]
[Aluminum alloy 7090s1, the world's top level, price: 20 achievement points]
After Mu Yang bought it absorbed it immediately!
All of a sudden, my brain was warm and I felt very comfortable. It was completely different from when I was doing gymnastics just now, but it was also refreshing.
After absorbing it, Mu Yang fell asleep holding Song Xuelu, who was full of elasticity.
She reclined on the soft pillow of Nishiki, her black hair spread like clouds, and her mouth was still smiling when she was asleep. Mu Yang's eyes swept across her butterfly-like eyelashes, rosy lips like begonias, and finally fell on her. The fragrant shoulders that were accidentally exposed, and the skin that was as white as milk.
gorgeous!
Mu Yang likes to see her sleeping position like this, and likes to hug her heart-warming S-curve.
Feeling the other person's different body temperature, Mu Yang fell asleep contentedly.
