Magic Number Alloys: Retro-Engineered?

What if........

What if the crash at Roswell New Mexico in July 1947 really happened. What if the government really did recover an extra-terrestrial space vehicle. What if the reports by witnesses that they handled some metallic material that had strange properties, from that crash, were really true. What if the government, or a compartmentalized small faction of the government has since taken that crash material and studied it for years, with the intention to retro-engineer the advanced technology for personal gain, for national security, for global reasons, etc. What if there was a plan, to begin to disclose this sensitive information to the public fifty years after the event. What if.....

I recently read a short article in SCIENCE NEWS JOURNAL that announces a new computational methodology for discovering new alloys with pretty spectacular properties. It sort of struck me as similar to what the witnesses of Roswell described seeing and handling. Could there be a connection?

Here is the article that I have copied ver batum.

Invent By Number: Researchers Predict, Then Produce Superior Titanium Alloys
written by Jessica Gorman, SCIENCE NEWS April19, 2003 Vol. 163, No. 16

Ingenious people have produced alloys since ancient times. By trial and error, they mixed metals and other elements until the whole came out better than any component alone. In recent years, some scientists have said that alloy development is a mature field with little room for improvement.

This week, however, researchers report a new method for making titanium-based alloys with many qualities far superior to those in any alloys previously known.

The team originally intended to develop materials for automobile parts, say Takashi Saito of Toyota Central Research and Development Laboratories in Nagakute, Japan. Instead, he and his coworkers wound up with materials that Saito says are too expensive for mass production in automobiles but have unusual properties suitable for a new generation of precision screws, eyeglass frames, medical devices, sporting goods, and spacecraft parts.

The alloys are strong yet unusually elastic, so they can deform more than other alloys and still return to their original shape. Engineers can also readily mold or bend the materials at room temperature into various shapes, a property called superplasticity.

The materials also possess two characteristics desirable in machine parts that experience wild fluctuations in temperature, such as those in a spacecraft. While most metals expand with any rise in temperature, the new alloys expand very little between -200 degrees C and -300 degrees C. Moreover, conventional alloys deform different amounts at different temperatures, but the new materials show about the same deformation whether it's -200 degrees C or 300 degrees C.

Saito and his coworkers report in the April 19 SCIENCE that they devised calculations with which they can predict what combination of elements would make an alloy with these properties. The researchers determined that a desirable titanium-based alloy must meet three criteria, which they call “magic numbers”, that are based on quantum mechanical calculations reflecting the behavior and arrangement of atoms and electrons.

The scientists add that an alloy meeting the criteria must be cold worked, or deformed by compression at room temperature, before it shows the extraordinary properties.

So far, Saito and his colleagues have made several titanium-based alloys that fit these criteria and possess the desired properties. The materials all include oxygen, and one, for example, also contains niobium, tantalum, and zirconium.

The new alloys' properties are “remarkable”, says Gary Shiflet of the University of Virginia in Charlottesville. In particular, he says, their superplasticity could eliminate the need for expensive machining techniques when shaping titanium alloys into products.

Perhaps more importantly, says Shiflet, the new report demonstrates the power of a computational method to predict alloys that never would have been made through trial and error.

Now, Shiflet asks whether the magic-numbers approach applies to other important classes of alloys, such as the nickel-based ones. “We will try it soon,” says Saito.

Of course, I do not KNOW that there is any connection. It just sounds a lot like the material that people in 1947 described: They would crumple it up in there hands and then it would return to its original shape. It was very, very sturdy, etc.

Also of note is that these new alloys were found by “magic numbers”, a computational method to determine the correct ingredients. To me, that sounds a lot like something that was retro-engineered.

Maybe someone out there has better research capabilities to look into this.

The appropriateness of chance is astounding.
