Chapter 265 Mu Yang Draws Big Cake Again

Chapter 265 Mu Yang Draws Big Cake Again

As the Chinese New Year is approaching, more and more migrant workers are returning home for the New Year these days.

Some migrant workers, when they called and chatted with their families, probably knew about the development of their families. They already knew about Youth Reservoir and Food Street, so they went back to have a look.

But some migrant workers are usually very busy, and they don’t have a lot of phone calls with their families, so they don’t know about the changes in their hometown. When they pass by the food street on their way home, they suddenly find:

When will there be a food court in the town?

When did the young reservoir become so impressive?

Wow!

What a change!

The terrain of Lujing Town is flat, with mountains but not high, and it is like spring all year round. The locals especially like to come out for supper. Even when there was no Xinghai Food Street in the town, there were still many roadside stalls and food stalls in the town, but they were not so large-scale and yet so distinctive. 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 by battery car. Tonight, there are still two to three hundred cars parked. Many of these diners come from the city or 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 viewed from the sky, this food street looks like a shining Milky Way.

The diners and tourists chatted and laughed, and 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 villagers in the town.

Mu Yang had nothing to do at night, so he accompanied Song Xuelu to the food street for a walk.

I didn't hang out with Song Xuelu for long, and I was 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, they exclaimed in surprise, as if they had discovered something new: Wow, everyone, come and see, there is a monster here!

Mu Yang felt weird when he heard a child shouting, so he shouted, but don't shout "Everyone come and see", it's not lively enough.

Some wage earners had never seen Mu Yang himself, but when they saw the commotion ahead, they heard that Mu Yang was coming, so they went over to have a look.

Mu Yang and Song Xuelu were recognized, so they had to warmly greet everyone.

"Hello folks, you don't need to be so enthusiastic." Mu Yang waved his hands and smiled, feeling a little bitter in his heart.

However, there were more and more people around, and thirty or forty people gathered within a few minutes. Mu Yang knew that he couldn't continue shopping, so he had no choice but to say: "Thank you for visiting the food street. If you have any good suggestions, you can ask The staff brought it up.

I will increase investment in my hometown. The current salary and treatment may not be as good as those of large companies in first-tier cities, but it is definitely much better than factories in Dongguan, Guangdong. At the same time, I hope that young people will join in the construction of their hometown. I believe that our Lujing Town will become better and better, and everyone’s income will be higher and higher. I believe that in a few years, every household will have a car and live in a better place. building. "

Mu Yang is not bragging, even without him, ten years later, not to mention every household has a car, it is really not a problem for one third of the households to have a car.

"Boss Mu is right!"

"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 their village, throwing away 6 million yuan at once. Muyang has donated to the elementary school and village roads in their village, and the middle school in the town. They are really 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, said a lot about how to imagine a better future life, and then took Song Xuelu away.

Tonight, he will take Song Xuelu home.

Well, the two of them haven't had sex for several days, and it's really a bit uncomfortable, especially on this cold night, it's perfect.

At eleven o'clock in the evening, the two finished a set of radio gymnastics they invented. Mu Yang was a little tired, lying on the bed like a "too", while Song Xuelu squinted and hugged Mu Yang like a gentle kitten. Yang fell 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 materials.

The titanium alloy factory building has been put into production, and Junfang will issue specific specification plates or profiles in the next year, and truly enter mass production;

The aluminum alloy plant is currently under construction and will be put into use around April.

It is impossible for an aluminum plant to produce only two types of materials, and Mu Yang needs to add more types. 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 automobile plates.

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, the strength is about 320MPa and 360MPa respectively, and they are not high-strength aluminum alloys.

But they have an advantage that they have good plasticity and can manufacture structures with complex shapes, so they are very good for complex structures such as four doors and two covers of cars.

Some structures require high strength, so 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 480 MPa, mainly 2 series (hard aluminum alloys) and 7 series (superhard aluminum alloys) series alloys.

Due to the different chemical composition, melting and solidification methods, processing technology and heat treatment process of the alloy, the properties of the alloy vary greatly.

Take the 7090 series with the highest strength in the current aluminum alloys as an example. For example, the M7090 aluminum alloy in the beautiful country has a maximum tensile strength of 855MPa, the EN aluminum alloy has a tensile strength of 840MPa, and the island country aluminum alloy has a tensile strength of 900MPa. The tensile strength of ultra-high-strength aluminum alloy is only 740MPa.

From the numerical point of view, even the same type of material has such a big difference in tensile strength!

900-740 = 160 MPa!

As far as the material is concerned, it is two grades worse.

Most of these high-strength aluminum alloys are used in aviation. For example, with the same strength structure, 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 of high-strength aluminum alloys.

Mu Yang plans to add another aluminum alloy material, that is, high-strength aluminum alloy, while he is idle at home and has nothing to do. First, organize the information in his head. It is estimated that the supercomputer and the human brain information conversion instrument will be available in March and April.

Of course, it does not mean that high-strength aluminum alloys can be used in components requiring 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°C!

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 is because it is close to the melting point, and its strength becomes weaker.

Therefore, the actual temperature range of aluminum alloy is below 150°C, and its performance will drop sharply if the working condition exceeds this temperature.

Of course, its advantages are low density, low price compared to titanium alloys, high output, and easier processing and welding.

According to the advantages and disadvantages of titanium alloy and super aluminum alloy, it is reasonably arranged on the aircraft.

For example, when an aircraft is flying at high altitude, the pressurized cockpit of the fuselage is under internal pressure, so it is necessary to use duralumin with high tensile strength and fatigue resistance as the skin material.

The frame of the fuselage is generally made of 7-series super duralumin, and the reinforced frame that bears a large 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 discs, 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% to 70% of the total metal materials used in aircraft (civil aircraft); if the requirements are higher, then increase the proportion of titanium alloys.

Mu Yang has mastered the production of titanium alloys TC4, TA7, and super-strength aluminum alloys, and can basically produce the main aviation materials by himself, so he has a certain foundation, does not depend on others, and will not be stuck by foreigners.

Of course, the key materials of the aircraft are high-temperature alloys, ultra-high-strength steels, and composite materials.

On the road of aviation materials, Mu Yang still has a long way to go, but at least he has taken the first step.

Thinking about this clearly, 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, adopting new melting and solidification methods, processing technology and heat treatment technology... The tensile strength can reach up to 960 MPa, and the plasticity can reach 12%...]

[Aluminum alloy 7090 S1, the world's top level, price: 20 achievement points]

After Mu Yang bought it, he immediately absorbed it!

Suddenly, my mind felt warm and comfortable. It was completely different from when I was doing gymnastics just now, but it was still refreshing.

After absorbing it, Mu Yang hugged Song Xuelu who was full of elasticity and fell asleep.

She was leaning on the soft brocade pillow, her black hair spread like a cloud, and there was a smile on her mouth when she was sleeping soundly. Mu Yang's gaze swept across her butterfly-like eyelashes, her lips were as red as a begonia, 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 posture like this, and likes to embrace that refreshing S-curve.

Feeling the other person's different body temperature, Mu Yang fell asleep contentedly.
