#Aluminum #powder-metallurgy produces parts with included amorphous aluminum oxide, providing higher strength and dramatically higher creep resistance than regular aluminum; hydrogen porosity is a danger.
on 02017-03-11#PDF of Flumerfelt’s 1998 dissertation on #aluminum #powder-metallurgy #materials processing; he finds that synthesizing his aluminum powder with gas atomization reaction synthesis ("GARS") was superior to existing commercial products, which were powdered by air atomization or gas atomization. Mentions that sintering aluminum powder in air has been shown to be possible but difficult by Storchheim (or maybe Storcheim) in 1974, in a paper called “Air sintering improves aluminum P/M economics”.
