摘　　要：亚稳β钛合金具有密度小、比强度高、可塑性好以及优良的耐腐蚀等力学和物理学性能,已经广泛应用在航空航天、生物医学和石油化工等领域。为实现对新一代高强度、高塑性钛合金的研发与应用,必须明确亚稳β钛合金力学性能与其变形损伤行为之间的联系。文章分析了亚稳β钛合金在变形损伤过程中的组织演变,概述了亚稳β钛合金的各种变形行为及各变形之间的联系,总结了不同的变形行为影响下对亚稳β合金力学性能的提升;然后阐述了亚稳β钛合金在动载荷下的损伤行为及其内部的组织演变,探讨了微观损伤对合金强化与失效之间的联系,以期对新型钛合金的研发与优化提出新见解。Metastable β titanium alloy has mechanical and physical properties such as low density,high specific strength,good plasticity and excellent corrosion resistance,and has been widely used in aerospace,biomedicine,petrochemical and other fields.In order to realize the development and application of a new generation of high-strength and high-plastic titanium alloys,the relationship between the mechanical properties of metastableβtitanium alloys and their deformation damage behavior must be clarified.In this paper,the microstructure evolution of metastable β titanium alloys in the process of deformation damage is analyzed,the various deformation behaviors of metastable β titanium alloys and the relationship between each deformation are summarized,and the improvement of the mechanical properties of metastable β alloys under the influence of different deformation behaviors is summarized.Then,the damage behavior and internal microstructure evolution of metastable β titanium alloys under dynamic load are expounded,and the relationship between microscopic damage and alloy strengthening and failure is discussed,in order to put forward new insights into the development and optimization of new titanium alloys.
