Preparation method of TC6 titanium alloy large-scale bar

The invention relates to the technical field of titanium alloys, in particular to a preparation method of a TC6 titanium alloy large-scale bar. The method comprises the steps that 1, a TC6 titanium alloy blank is subjected to one-heating-number blooming forging through forging equipment, water cooling is conducted, and a blank A is obtained; 2, the blank A is subjected to 2-3 heating number single-phase region intermediate modified forging and 7-9 heating number two-phase region intermediate modified forging, water cooling is adopted, and a blank B is obtained; 3, the blank B is subjected to rolling forming and air cooling; carrying out isothermal aging to obtain a titanium alloy bar matrix; and 4, the titanium alloy bar base body is sequentially subjected to laser shot peening treatment and plating treatment, and the TC6 titanium alloy large-scale bar is obtained. In the scheme, the prepared TC6 titanium alloy large-scale bar has excellent mechanical strength and wear resistance. 本发明涉及钛合金技术领域，具体为一种TC6钛合金大规模棒
