Method of fabricating strips or foils, respectively, from TiAl6V4
摘要:
A method of fabricating a superplastically formable strip or a superplastically formable foil from TiAl6V4 with a thickness of no more than 0.9 mm, preferably less than or equal to 0.5 mm, comprises the steps: a) hot rolling a sheet metal made of TiAl6V4; b) thermal pre-treatment of the hot-rolled sheet metal at a temperature between 650 and 850° C.; and c) cold rolling the hot-rolled and thermally pre-treated sheet metal at a forming rate of at least 30%, wherein the forming rate per single pass amounts to between 1 and 15%, to form a strip or a foil with a thickness of no more than 0.9 mm, wherein the cold-rolled strip or the cold-rolled foil is not annealed.
