Abstract
A multiphase, high-temperature material contains an intermetallic base alloy of the Ti.sub.3 Al type, which is intended especially for use in heat engines such as internal combustion engines, gas turbines and aircraft engines. The material contains from 44 to 73 atom % titanium, from 19 to 35 atom % aluminum, from 2 to 6 atom % silicon, and from 5 to 15 atom % niobium. The desired microstructure is attained by heat treating the alloy at between 800.degree. and 1100.degree. C.
