Abstract

Read online

Individual addition of O or Al is known to deteriorate ductility of Ti alloys, especially at cryogenic temperatures. Here the authors demonstrate a counter-intuitive effect where significant addition of both Al and O substantially improves both strength and ductility in a Ti-6Al-0.3 O ternary alloy.
