Summary: | The invention discloses a preparation method of an ultrahigh strength titanium alloy hot-rolled bar. The preparation method comprises the following steps: S1, heating the ultrahigh strength titanium alloy hot-rolled bar to the temperature which is 15-20 DEG C lower than the beta phase transformation point temperature, and carrying out thermal insulation; and S2, heating the ultrahigh strength titanium alloy hot-rolled bar after thermal insulation treatment to the temperature which is 10 DEG C higher than the beta phase transformation point temperature, and carrying out multi-pass rolling to obtain the ultrahigh strength titanium alloy hot-rolled bar. According to the preparation method, a beta grain structure is obtained on the surface layer of the ultrahigh strength titanium alloy hot-rolled bar through two-step heating, so that impact of the ultrahigh strength titanium alloy hot-rolled bar to a roller is reduced during the rolling process, and abrasion of production equipment is lowered; the beta grain stru |
