DIRECT ROLLING OF CAST GAMMA TITANIUM ALUMINIDE ALLOYS

摘要

A process for producing sheets of .gamma.-TiAl includes the steps of forming a melt of a .gamma.-TiAl alloy; casting the T-TiAl alloy to form an as-cast .gamma.-TiAl alloy; encapsulating the as--cast y-TiAl alloy to form an as-cast .gamma.-TiAl alloy preform; and rolling the as-cast .gamma.T-TiAl alloy preform to form a sheet comprising .gamma.-TiAl.
