NASA's Additive Manufacturing Alloys for High Temperature Applications Webinar

[@masatoizumi926]

Great stuff. Is there any way to extrapolate the creep properties at higher combustion temperatures? Thank you

[@MrPruske]

Thank you for sharing this info

[@gumtreenut1]

Fantastic material design. Can you provide a hint as to what this will allow NASA to do that it couldn’t before?

[@aaron41]

One of the goals is to build jet engine components to take higher temperatures, which has efficiency benefits.

The Yitrium oxide addition seems like an inspired solution. I am looking for information on 3d printing tantalum Hafnium carbide alloys and Hafnium carbide Oxide compounds. I am in need of a rocket engine that will not melt above 7,000 F or deform below 6,000 under 1,000 bar.

no known metal on earth meets your reqts. spaceX's sx-500 showing solid results in deformation/strength up to 800bar. with micro additions of B, Yt and other wizardy Elements, perhaps HIP and triple melt VAR processes will rise to the occasion.

@@kenw8875 The melting temperature of Tantalum Hafnium Carbide is around 7,140 to 7,400 degrees Fahrenheit . I don't know the creep strength temperature, I hope it can sustain 1000 bar at 6,600 degrees.

Graphite will sure work for a burn of a few seconds

What toxicity issues exist for the Cr and Co, and for the YO nanoparticles that would need consideration in a manufacturing environment?

[@Michael-ij6kg]

Try not to breath it in or get it on you.

[@aaron41]

Respirators are a must any time you work with nanoparticles.

[@Dreamtaker509]

I make these alloys! I am an Iner Gas Atomization melter.
