Preparation method of short-process alloy forge piece

The invention discloses a preparation method of a short-process alloy forge piece, and relates to the field of alloy forge piece preparation, solution treatment is carried out, an alloy material is placed in a vacuum furnace to be calcined and melted, heat preservation is carried out for two hours, a treated alloy blank is subjected to directional solidification from top to bottom through a directional cooling technology, and then homogenization treatment is carried out; carrying out primary aging treatment on the alloy to obtain a short-process alloy homogenized blank, transporting the alloy to a deformation die after primary aging treatment, carrying out hot forging deformation under the condition that the deformation amount is 20-30% to obtain a deformed alloy blank, transporting the deformed alloy blank to a die forging die to carry out die forging, and carrying out subsequent heat treatment after die forging, a large amount of heat of the solidification part is taken away through the liquid metal to achi
