中文摘要：近年来,钛及钛合金由于具有一系列优异的性能受到了广泛的关注.与其他合金体系不同,钛合金中存在着两种同素异形体和一系列亚稳相.在总结近年来研究成果的基础上,综述了钛合金中存在的各种相变过程,其中不仅涉及到了一些常见的相,还有部分较少被报道的相.对于钛合金中只涉及α相和β相的相变,不仅介绍了从β到α相的转变过程,还对其逆相变进行了描述,并阐述了应力在其中发挥的作用.对于亚稳相,从亚稳相的形成机理、其形成对微观结构和合金力学性能的影响等方面分别进行了论述.此外,还针对目前钛合金在发展过程中存在的问题提出了几点意见和建议.

外文标题：Phase transformation in titanium alloys:A review

外文摘要：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 βphases,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.
