有利于提高加工硬化率,从而提高抗拉强度和伸长率[13-14].2012年,PRIMA等[15]首次将钢铁材料中发展得比较成熟的相变诱导塑性(TRIP)和孪晶诱导塑性(TWIP)的思路引入到亚稳β钛合金的合金设计中,通过变形过程中应力诱发β→α″,ω相变以及{332},{112}变形孪晶的产生实现动态细晶化,使得加工硬化率大幅提升.他们所设计的Ti-Mo,Ti-Cr基系列合金均呈现了优异的塑性...晶/马氏体边界形成的长条ω相在形貌和分布上都与亚稳β钛合金中常见的颗粒状ω相不同.HU等[20]采用第一性原理密度泛函理论计算过不同Nb含量的Ti-Nb合金中β相与ω相的能量差,发现对于Nb含量低于23.5%(摩尔分数)的合金,其ω相的能量更低,更稳定.因此该计算结果表明,β相到ω相的转变应该是自发的.而实验观察到的现象则显示,β→ω相变只出现在{112}孪晶或α″马氏体的边界上,也即该相变需要变......
