Abstract

Alloy is made of titanium aluminate in which a minor fraction of the aluminium and titanium atoms is replaced by other atoms. It contains (by atomic %) 44 to 49 of aluminium, 0.5 to 3 of zirconium. 0.5 to 2 of iron, 0.5 to 2 of molybdenum, 0.2 to 0.5 of silicon and 0 to 3 of niobium. An independent claim is also included for: heat treatment of the alloy.
