| Abstract: | Various heat-treatments has been carried out for high-temperature structural intermetallic alloys comprised of L21-type (Co,Ni)2AlTi and L12,-type (Co, Ni)3 (Al,Ti) ordered phases in the quaternary system Co-Ni-Al-Ti. The optimum heat- treatment parameters were found out through microstructural analysis, and the properties of the intermetallic alloy have been improved. |
