Evaluation method for selective laser melting forming performance of titanium alloy material

The invention discloses a method for evaluating selective laser melting forming performance of a titanium alloy material, and relates to the technical field of selective laser melting forming. The method comprises the following steps: (1) preparing a titanium alloy cast ingot; (2) the titanium alloy cast ingot is subjected to quenching treatment; and (3) a mechanical property tensile test bar is taken, the titanium alloy cast ingot treated in the step (2) is subjected to room-temperature stretching, the ductility of the titanium alloy cast ingot at the room temperature is obtained, the ductility of the titanium alloy material in the quenching state is compared, and the formability of the titanium alloy material is evaluated. By adopting the method, the selective laser melting forming performance of the titanium alloy material can be identified, the cost is low, the process is short, and the efficiency is high. 本发明公开了一种钛合金材料激光选区熔化成形性能的评价方法，涉及激光选区熔化成形技术领域。该方法包括：步骤(1)：制备钛合金铸锭；步骤(2)：对所述钛合金铸锭进行淬火处理；步骤(3)：取力学性能拉伸试棒
