为了改善钛合金的组织和机械性能,提出了不同的热机械处理方法。热机械处理时的强化机理与强化热处理一样,是由相比容差造成的相硬化和由分解弥散性以及相界长度决定的相界面问的弥散强化。采用不同热机械处理方案的强化效果取决于合金的化学成份和相成份。高温热机械处理(加热→变形,接着水冷,在冷却过程中发生相变→时效)时的最大强度和最大强
In order to improve the microstructure and mechanical properties of titanium alloys, various thermomechanical treatment methods have been proposed. As in the case of intensive heat treatment, the mechanism of strengthening during thermomechanical treatment is dispersion strengthening caused by phase hardening caused by relative tolerance and interfacial interface determined by decomposition dispersion and phase boundary length. The effect of strengthening with different thermo-mechanical treatments depends on the chemical composition and phase composition of the alloy. Maximum strength and maximum strength at high temperature thermo-mechanical treatment (heating → deformation, followed by water cooling, phase change during aging → aging)
