TITANIUM ALUMINIDE ALLOYS

摘要

Alloys based on titanium aluminides, such as gamma (TiAl) which may be made through the use of casting or powder metallurgical processes and heat treatments. The alloys contain titanium, 38 to 46 atom % aluminum, and 5 to 10 atom % niobium, and they contain composite lamella structures with B19 phase and beta phase there in a volume ratio of the B19 phase to beta phase 0.05:1 and 20:1.
