Development of a Hot Working Simulator and Application to TiAl Intermetallic Compounds

Abstract

The purpose of the study is to develop a new simulation testing machine for hot working brittle materials such as intermetallic compounds.
Various factors which are the requisites for hot working these materials have been argued, and a new simulator which satisfies these requirements has been developed.
TiAl intermetallic compound has been used to verify the ability of the simulator. It was found in this test that the stress-strain curve of TiAl single phase mateials is quite different from that of TiAl+Ti₃Al two phase materials at high temperatures.
