Abstract

TiAl base alloys have been considered as new high temperature structural materials for promising application in aerospace and high-performance engines. The properties, applications of γ-TiAl base alloys have been reviewed, and the progress in fundamental aspects of these materials has been outlined. Subsequently, the process and mechanical properties of PM γ-TiAl base alloys have been introduced. Finally, the advantages and development of PM process in preparing and near net shaping of γ-TiAl base alloys have been described by citing the fabrication of γ-TiAl base alloy valves and plates.
