Yamamoto further said “We are going to use this process in our new battleship.”

Pretty cool. How big is the market for welding stainless to aluminum? Is there a need in automotive?

Those are some pretty fast weld speeds.

A space -battleship that can go toe to toe with the Gamelons.

Next step:

Transparent Aluminum..................

Ping to Pollard who will understand this.

...capable of withstanding separation stress of up to 17404.5 pounds per square inch on average...

17.4 ksi is less stress than steel and aluminum alloys can typically take on their own (yes, I know some aluminums are less). So, you make an alloy that is weaker than the individual components.

Which is good for ‘Crumple Zone’ materials to absorb shock.....................................

[Macho MAGA Man]

Yep! Scotty already has the formula.

Yes there is. But this hybrid only has a yield strength of 17ksi which is well below either aluminum or steel.

We are going to use this process in our new battleship.

Lots of that going over most individuals’ heads here. It is even more coincidental that is was called Fusion. Fission would be more apropos.

Could this be used to 3D print something like, oh I don’t know, maybe a gun barrel or receiver or something like that? Asking for a friend.

[ByteMercenary]

If you are thinking Star Trek, I also thought something like that. Hoe far are we from when someone can walk up to a box, insert your debit card, key the microphone and say “I need the right upper swing arm for a 2012 Lincoln Navigator.”

[Macho MAGA Man]

Yes, I had Trek on my mind saying that. Yes,it would be cool to be able to do something like that.

.......this hybrid only has a yield strength of 17ksi which is well below either aluminum or steel.

Yield or tensile? If the writer meant tensile, then the yield will be well below that. Might have a use attaching decorations, but structural? No thanks.

[ProtectOurFreedom]

It was the “Yamamoto” reference.

[Reverend Wright]

I guess I should have said tensile, although for more brittle materials, there seems to be is little or no separation between them.

This is applied research in the lab, but I am not sure what problem this process is supposed to solve.

GM is already spot welding steel to alum.

Computer! Show me the formula for Transparent aluminum!

R.B. Aye, here you be ye ruddy dustmop! :)

https://en.wikipedia.org/wiki/Aluminium_oxynitride

Chemical formula (AlN)x·(Al2O3)1−x, 0.30 ≤ x ≤ 0.37

Aluminium oxynitride is used for infrared-optical windows, with greater than 80% transparency at wavelengths below about 4 micrometers, dropping to near zero at about 6 micrometers.[8] It has also been demonstrated as an interface passivation layer in some semiconductor-related applications.[9]

Aluminium oxynitride has less than half the weight and thickness of glass-based transparent armor.[10] Aluminium oxynitride armor of 1.6-inch (41 mm; 4.1 cm) thickness is capable of stopping .50 BMG armor-piercing rounds, which can penetrate 3.7 inches (94 mm; 9.4 cm) of traditional glass laminate.[8][11]

In 2005, the United States Air Force began testing aluminium oxynitride-based armor.[12]

Other lightweight high strength metals; alloy of Aluminum and Scandium is light and weldable and is less prone to corrosion than aluminum. Titanium is strong and not subject to corrosion. Niobium Steel alloy.
