三元β-亚稳钛Ti-9 Mo-6 W（重量%）是设计好的一个非常高的加工硬化率接近2100 MPa和大于35%的均匀变形记录，由于相结合的相变诱导塑性和孪生诱导塑性效应。本文对变形过程进行了详细的显微组织分析。通过< 113 >力学性能测试，确定了不同的机制：{332}机械孪晶、应力诱发的Ω相和应力诱发的α“马氏体，形成了具有特殊协同特征的复杂变形组织网络。(C)2014 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
A ternary beta-metastable titanium Ti-9Mo-6W (wt.%) was designed. A very high work hardening rate close to 2100 MPa and a uniform deformation larger than 35% were recorded, thanks to combined transformation-induced plasticity and twinning-induced plasticity effects. In this paper, detailed microstructural analysis was performed to understand the deformation process. Various mechanisms, {332} < 113 > mechanical twinning, stress-induced omega phase and stress-induced alpha '' martensite were identified after mechanical testing, resulting in a complex network of deformed microstructures with very special synergetic features.
