Abstract
PURPOSE:To improve the hot workability of the titled material by incorporating specific amounts of Cr and Fe into the material consisting essentially of a TiAl intermetallic compound. CONSTITUTION:One or two kinds between 0.1-20atom.% Cr and Fe are incorporated into the material consisting essentially of a TiAl intermetallic compound and the balance is constituted of inevitable impurities. One or more kinds among 0.1-5% Mn, Ag and V are furthermore incorporated into said compsn. at need. In this way, the coarse needle structure of the TiAl intermetallic compound is transformed into the fine spheroidal structure, by which the hot workability of the material is improved without deteriorating the strength characteristics.
