研究810℃固溶后冷却速度对TB6钛合金的组织和塑性的影响。结果表明:当冷却速度较快时,β相来不及析出α相而生成α“(α”是淬火马氏体);在拉伸过程中,亚稳定β相产生应力诱发马氏体相变为材料带来较高的塑性;当冷速减慢时,材料完成β→α的转变,造成材料的低塑性。故水冷条件下能获得最佳的塑性。 The effect of cooling rate at 810 ℃ on the microstructure and plasticity of TB6 titanium alloy was studied. The results show that when the cooling rate is high, the α phase precipitates less than the α phase (α is the quenched martensite). During the stretching process, the metastable β phase produces stress-induced martensitic transformation Bring higher plasticity to the material; when the cooling rate slows, the material completes the transformation of β → α, resulting in the low plasticity of the material. Therefore, under the conditions of water can get the best plasticity.
