Abstract (en)

[origin: EP2272993A1] The method involves manufacturing a forge piece from a column-shaped or rod-shaped raw material of titanium-aluminum alloy. The raw material is heated at temperature higher than 1150 degree Celsius by electricity supply or induction heat such that the forge raw material is transformed to different cross-sectional area in over length range, where the raw material is heated at deformation temperature in multiple steps. A covering part is provided with oxidation zirconium to decrease surface temperature fall of the forge piece. Ratio of oxidation zirconium is greater than 70 weight percentage.
