Method for manufacturing TiAl intermetallic compound component based on Ti elemental powder and Al elemental powder

A method for manufacturing TiAl intermetallic compound component based on Ti elemental powders and Al elemental powders relates to a method for manufacturing a TiAl intermetallic compound component, and belongs to the technical field of metal component precise forging and forming processes. By adopting a novel technological process based on Ti/Al elemental powder forging and subsequent reactive sintering, the invention aims to solve the problems of great forming difficulty, being difficult for existing mould materials to satisfy process requirements, high process cost and huge energy consumption in the manufacturing process of the TiAl intermetallic compound component by the traditional isothermal forging method. The method comprises the steps of: I, mixing powders; II, manufacturing Ti/Al powder preforms; III, precisely mould-forging and forming Ti/Al powder body under low temperature; IV, reactively sintering forged Ti/Al powder pieces; and V, repressing and reshaping under high temperature to obtain the TiAl intermetallic compound component. The invention mainly utilizes the Ti elemental powders and Al elemental powders to manufacture the TiAl intermetallic compound component.
