钛合金是优异的轻金属工程材料,具有低密度、高比强度、高断裂韧性及良好的耐腐蚀性能。过去很长一段时间,改善钛合金的室温强度和延展性是先进结构材料发展的一个重大课题。氧对钛合金力学性能的影响是可以增加其屈服应力和断裂应力,但会降低其塑性。因此,探讨是否可以克服氧对钛合金力学性能的有害影响是一件有意义的工作。
Titanium alloy is excellent light metal engineering materials, with low density, high specific strength, high fracture toughness and good corrosion resistance. For a long time to come, improving the room temperature strength and ductility of titanium alloys is a major issue for the development of advanced structural materials. The effect of oxygen on the mechanical properties of titanium alloys can increase its yield stress and fracture stress, but reduce its plasticity. Therefore, to explore whether it can overcome the harmful effects of oxygen on the mechanical properties of titanium alloys is a meaningful task.
