Title:
HOT WORKING METHOD FOR IMPROVING HIGH-SPEED IMPACT RESISTANCE OF TWO-PHASE TITANIUM ALLOY
Document Type and Number:
WIPO Patent Application WO/2023/016143
Kind Code:
A1
Abstract:
The present invention relates to the technical field of titanium alloy material preparation. Disclosed is a hot working method for improving high-speed impact resistance of a two-phase titanium alloy. The hot working method for improving high-speed impact resistance of a two-phase titanium alloy comprises the following steps: 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 present invention, 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 α+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. The hot working method of the present invention can effectively solve the problems that the existing two-phase titanium alloy plates are low in strength and poor in high-speed impact resistance.
