Lu Yuan did not debate online with experts and professors who questioned him, and he liked to speak with facts.

So he directly invited journalists from the world's major media to participate in the upcoming salvage event.

He believed that with the unidentified truck coming out of the water, the whole world would be shocked again.

At that time, the doubts on the Internet will naturally disappear.

Naturally, the reporters who were invited were also very excited.

As we all know, every salvage operation that Lu Yuan participated in would cause a sensation in the world.

They believe that even if this salvage has nothing to do with the Mu continent and aliens that are spreading all over the world, it must be a very significant discovery.

Three days later, Anthony and his crew appeared in the Cook Islands in the world's most advanced salvage ship, the Yingzhou.

With the arrival of the "Yingzhou", the Cook Islands have also become more lively.

The Cook Islands, which originally had a population of less than 20,000, flooded with more than 30,000 people in just a few days.

This salvage operation has even attracted the attention of countries around the world.

The crew is now very tired after a long voyage.

Therefore, Lu Yuan did not start the salvage operation immediately.

Instead, the crew was given two days off.

On the third day, Lu Yuan led the crew to drive the "Yingzhou" to the salvage site.

The salvage site is located on the high seas, 500 km east of the Cook Islands.

Lu Yuan was accompanied by more than 30 journalists and photographers from all over the world.

Fortunately, the "Yingzhou" is large enough, and there are more than 30 people on board, which will not affect the next operation.

The reporters who did not board the Yingzhou chose to take other ships to follow the Yingzhou to the salvage area.

Ships in the surrounding waters who knew about the salvage operation also sailed to the salvage area.

When Lu Yuan and the others started to act, dozens of ships had already gathered near the Yingzhou. There are even several warships among them.

When the reporters and photographers were ready, Lu Yuan commanded the crew to start the salvage operation.

Because this is a very difficult deep-sea salvage, the best way to do it without exposing yourself is to use robots.

After helping Anthony find the location of the salvage, Lu Yuan handed over the specific work to Anthony.

Anthony is also not polite, in fact, if Lu Yuan does not cheat, his salvage experience and skills are much stronger than Lu Yuan.

After Anthony took over the reins, he did not immediately carry out the salvage.

Instead, a large number of detection devices were put into the surrounding seas.

His aim was to find out the surrounding hydrology and geology.

Deep-sea salvage has very high technical requirements, and any sloppiness may lead to salvage failure.

Deep-sea salvage is an absolutely high-tech industry.

The requirements for equipment, technology and personnel are very high.

It took a day and a half just to check the surrounding sea conditions and the geology of the seabed.

At noon the next day, Anthony dropped a deep-sea robot on the salvage target.

These robots are purpose-built, and their exterior materials are all cast in titanium.

Without the use of titanium, even robots would not be able to withstand the pressure of the deep sea.

Of course, they are also very beautiful at a very good price, except for the scientific expeditions supported by the government.

Only Lu Yuan's Ocean Exploration Company has a deep-sea salvage robot.

As soon as these robots appeared, they made their peers in the treasure exploration world show expressions of envy, jealousy and hatred.

Although they are envious and jealous, they are powerless, because these things are not used by them at all.

A lot of exploration companies don't make a decade worth a robot.

With the help of these deep-sea salvage robots, the salvage operation went very smoothly.

By noon on the third day, the strange truck had been salvaged and put onto the ship.

When it first came out of the water, many people didn't care.

I was even wondering why Lu Yuan invited everyone to come and salvage a car.

A reporter who knew a lot about materials science soon discovered that the car was wrong.

"Memory Metal!"

He couldn't help but exclaim after taking a closer look.

"William, what is memory metal?"

A reporter who has a good relationship with him asked.

The journalist, William, was so excited that he simply walked up to the camera and introduced memory metal to the world's audience.

"Memory metal generally refers to a special metal material that can recover its original macroscopic shape after plastic deformation occurs in a certain temperature range. ”

"Memory metal is also called shape memory alloy.

In the 70s of the last century, an alloy with the function of "memory" shape appeared in the world's materials science.

Memory alloy is a very special metal bar that is very easy to bend, so we put it in a glass jar with hot water and the metal bar rushes forward, and when we put it in cold water, the metal bar returns to its original shape.

In a glass jar filled with cold water, a spring is stretched out, and when the spring is placed in hot water, the spring automatically retracts again.

In cold water, the spring returns to its original state, while in hot water, it shrinks, and the spring can be stretched and contracted an infinite number of times, contracted and then pulled away.

These are made of a smart metal with memory, and its microstructure has two relatively stable states.

The alloy can be changed into any shape you want at high temperatures, and the alloy can be stretched at lower temperatures, but if it is reheated, it remembers its original shape and changes back. This material is called memory metal.

The general memory metal is mainly a nitinol material.

For example, a spiral superalloy is annealed at high temperatures, and its shape is in a spiral state.

At room temperature, even if it is forcibly straightened with great force, as soon as it is heated to a certain "metamorphosis temperature", the alloy immediately reverts to its original spiral form as if it remembers something.

Speaking of which, William was afraid that the audience would not understand, so he continued to summarize:

Shape memory alloys can be divided into three types:

The first is the one-way memory effect, which is a shape memory alloy that is deformed at a lower temperature and can return to its pre-deformation shape after heating, and this shape memory phenomenon that only exists in the heating process is called the one-way memory effect.

The second is the two-way memory effect. Some alloys regain the shape of the high-temperature phase when heated and the low-temperature phase shape when cooled, which is called the two-way memory effect.

The third is the whole-process memory effect, which restores the shape of the high-temperature phase when heated, and changes to the shape of the low-temperature phase with the same shape but opposite orientation when cooled, which is called the whole-process memory effect.

The building material of the car that Lu Yuan salvaged this time is obviously the full-field memory alloy, which should not be said to be stronger than the existing full-process memory alloy. It's simply a whole new memory alloy.

I believe that the emergence of this alloy will definitely bring about a revolutionary change in material technology.

Originally, everyone had no concept of memory alloy, but with William's explanation, everyone really understood the value of this car.

"William, you mean to say that this car is priceless?"

"Of course, of course, it's hard to imagine that such a treasure could be hidden in this desolate sea!"

"Lucy, do you know that if humans can master the technology to make this material, do you know what that means, it will allow humans to build bigger and faster spacecraft, and we humans may be able to go further in the universe. ”

"Lucy, I've decided, after this time, I'm going to resign, and I'm going back to work at the institute......"

"Oh, William, you're not crazy, are you?"

"Of course, of course I didn't go crazy, I was working at the institute back then, and I thought I would call my teacher right away......"

After William explained the memory metal to the audience, he couldn't contain his excitement and began to become incoherent.

......

"Hi, Professor, I'm William......"

"William, aren't you going to be a journalist......

"Professor, I'm sorry I failed to live up to your expectations...... But this time I decided to go back to the institute....."

"William, are you serious?"

"Yes Professor, you can turn on the TV ......"

"Oh, mygod, isn't it really April Fool's Day, are you sure...... Okay, okay, I'll come over tomorrow, no, I'll bring my team over now....."

"Professor, I'm afraid we don't have a way to study it now, these things still belong to Lu, and no one can take these things away without his permission......"

"Shet, these damn capitalists......"

"Professor, Lu Ke is not a capitalist......

......

The same scene not only happened between William and his teacher, but in just half a day, the news that Lu Yuan and his exploration company salvaged a car of unknown origin and super memory metal in the Pacific Ocean spread throughout the archaeological and materials science circles.

The next day, a large number of research institutes submitted research applications to Lu Yuan.

Lu Yuan didn't think about what to do for a while, so he just asked the major research institutes to apply to the "Kara Imperial Research Association" first.

At the same time, Lu Yuan once again released to the world photos and videos of the items he obtained from this car.

These things spark people's curiosity instantly.

"Oh, mygod, I bet these things must have been left behind by aliens. ”

"No, no, no, I think these things should be the ...... left by Mu Continent"

"It shouldn't be left by Mu Dalu, you take a closer look, the words on the body, and the words on other things, are different from the words found elsewhere!"

"I don't think it's left by the Mu Continent, but could it be the Atlanteans?"

"Atlantis, what the hell is this?"

"Is it really possible, isn't it true that the Atlanteans possessed oraldrope and memory metal?"

"Is it really possible....."

"I think it's probably the ..... left by the Lemurians"

"Let's talk about it, Lu Yuan explores everywhere every day, will he know more?"

"Why don't we ask him!"

Soon many netizens began to @Lu Yuan on the Internet......
