ABSTRACT:
High-temperature materials, based on alloyed intermetallic NiAl, have the following chemical composition (values in % by weight):26-30 Al,1-6 Ta,0.1-3 Fe,0.1-1.5 Hf,0.01-0.2 B,0-1 Ti,0.1-5 Pd,with the remainder Ni and production-related impurities. The materials have excellent properties, in particular good strength and extremely high oxidation resistance, at very high temperatures of 1300° C., for example.
