摘要
β钛合金广泛应用于航空航天、海洋、军事和生物医学等高性能和先进工程领域,但现行工艺应用对其性能提出了更高的要求。热处理工艺可以显著提升β钛合金的性能,对近年β钛合金热处理工艺进行综述。首先系统综述了β钛合金的主要相构成及相变,然后分别对固溶时效典型热处理工艺、塑性变形机制以及新发展的预变形时效工艺对组织演变和性能的影响进行了阐述分析,并对β钛合金热处理工艺的发展趋势进行展望。
β titanium alloy is widely used in the fields of high performance and advanced engineering such as aerospace, marine, military and biomedical, but the current process application puts forward higher requirements for its properties. β titanium alloy can be strengthened by heat treatment. The heat treatment process of β titanium alloy in recent years was reviewed. Firstly, the main phase composition and phase transformation of β titanium alloy were systematically overviewed. Then, the effects of typical heat treatment process, plastic deformation mechanism and newly developed pre-deformation aging process on microstructure evolution and properties were described and analyzed. Finally, the development trend of heat treatment process of β titanium alloy was prospected.
