英文摘要：

{332}〈113〉deformation twinning is a unique deformation mode which can have some special features and a strong influence on the mechanical properties for metastable β-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.
