Abstract

Due to a series of exceptional properties, titanium and titanium alloys have received extensive attention in recent years. Different from other alloy systems, there are two allotropes and a sequence of metastable phases in titanium alloys. By summarizing the recent investigations, the phase transformation processes corresponding to the common phases and also some less reported phases are reviewed. For the phase transformation only involving α and β phases, it can be divided into β→α transformation and a reverse transformation. The former one has been demonstrated from the orientation relationship between α and β phases and the regulation of α morphology. For the latter transformation, the role of the stress has been discussed. In terms of the metastable phases, the mechanisms of phase formation and their effects on microstructure and mechanical properties have been discussed. Finally, some suggestions about the development of titanium alloys have been proposed.

钛合金中的相变：综述

由于钛和钛合金具有一系列特殊性能，近年来受到广泛关注。与其他合金体系不同，钛合金中存在两种同素异形体和一系列可转移相。通过总结最近的研究，我们回顾了与常见相以及一些报道较少的相相对应的相变过程。对于只涉及 α 和 β 相的相变，可分为 β→α 相变和反向相变。前者已从α相和β相的定向关系以及α形态的调节中得到证实。对于后一种转变，讨论了应力的作用。在可转移相方面，讨论了相的形成机制及其对微观结构和机械性能的影响。最后，对钛合金的发展提出了一些建议。

期刊介绍： The Transactions of Nonferrous Metals Society of China (Trans. Nonferrous Met. Soc. China), founded in 1991 and sponsored by The Nonferrous Metals Society of China, is published monthly now and mainly contains reports of original research which reflect the new progresses in the field of nonferrous metals science and technology, including mineral processing, extraction metallurgy, metallic materials and heat treatments, metal working, physical metallurgy, powder metallurgy, with the emphasis on fundamental science. It is the unique preeminent publication in English for scientists, engineers, under/post-graduates on the field of nonferrous metals industry. This journal is covered by many famous abstract/index systems and databases such as SCI Expanded, Ei Compendex Plus, INSPEC, CA, METADEX, AJ and JICST.
