摘要
{332}<113>变形孪晶是亚稳β型钛合金变形过程中的一种独特变形机制。该类型孪晶具有特殊性质并且对亚稳β型钛合金力学性能具有显著影响。本文总结了{332}<113>变形孪晶的研究状况和特性,重点介绍了{332}<113>变形孪晶形成的几种代表性模型。通过分别对这些模型的假设条件以及需要进一步解释和验证的科学问题进行分析,旨在为理解和揭示{332}<113>变形孪晶的变形机制提供有用的参考信息。
{332}〈113〉deformation twinning is a unique deformation mode which can have some special features and a strong influence on the mechanical properties for metastableβ-type titanium alloys.{332}〈113〉deformation twinning has already got more and more attention.The research situation and observed characteristics for the{332}〈113〉deformation twinning are summarized in this paper.Some typical models for the{332}〈113〉twinning are reviewed,and their assumptions and remaining prob-lems are presented so as to provide useful information for understanding and revealing the deformation mechanism of{332}〈113〉deformation twinning.
