Summary: | The invention discloses a process method for efficiently preparing a high-strength and high-impact-resistance titanium alloy forge piece through beta forging. The process method comprises the steps that firstly, a titanium alloy cast ingot is subjected to first-heating-number cogging forging after being subjected to heat preservation, and a first forging stock is obtained; 2, heating the first forging stock to 20-30 DEG C below a beta phase transformation point, and carrying out first heating number upsetting and drawing forging to obtain a second forging stock; thirdly, the second forging stock is heated to a beta-phase region to be subjected to two times of uniform drawing-out forging, and a third forging stock is obtained; and fourthly, the third forging stock is subjected to solid solution and aging heat treatment, and the titanium alloy forge piece is obtained. According to the method, grain refinement is achieved through one-heating-number cogging forging and one-heating-number upsetting and drawing for |
