A process for the production of strips or sheets of TiAl6V4

A method for manufacturing a superplastically formable strip or a superplastically formable foil of TiAl6V4 with a thickness of not more than 0.9 mm, preferably less or equal to 0.5 mm, comprising the steps of: a) hot rolling a sheet of TiAl6V4, b) thermal pretreatment of the hot-rolled sheet at a temperature of 650-850 ° C and c) cold-rolling the hot-rolled and thermally pre-treated sheet at a reduction of at least 30%, wherein the forming rate per single pass amounts to 1-15%, to a tape or a sheet having a thickness of not more than 0.9 mm, wherein the cold-rolled strip or the cold-rolled foil is not annealed.
