Abstract
A thermal processing method for improving high-speed impact resistance of a two-phase titanium alloy includes the steps of: a, heating a two-phase titanium alloy slab blank step by step; b, using a reversing rolling mode to first perform transverse rough rolling, and then reverse a plate blank for longitudinal rolling, and c, water-cooling the rolled plate, and then performing solution heat treatment and aging treatment. According to the method, the anisotropy of transverse and longitudinal properties of the finished plate can be reduced by using a method of two-stage rolling in a β-phase region and an a+β two-phase region, and in combination with rapid cooling after rolling and solid-solution and aging strengthening heat treatment, high strength and excellent high-speed impact resistance of the product can be ensured, and the protective performance of the material is greatly improved.
