摘　　要：面心立方结构钛是一种亚稳相,最早发现于超薄钛膜。除此之外,钛及钛合金在经历大塑性变形之后,也常常会发生hcp→fcc钛及钛合金的相变。近年来,大量研究报道了钛及钛合金经冷轧、压缩、拉伸和球磨等加工后观察到面心立方结构钛。为此,对近几十年来面心立方结构钛的制备方法、相变机理及其变形行为的研究进展进行了详细介绍。现有研究已证实,面心立方结构钛不仅能够协调材料的变形,而且有利于材料强度的提高。Face centered cubic titanium is a metastable phase,which was first found in ultrathin titanium films.The hcp→fcc phase transformation often occurs in titanium and titanium alloy after severe plastic deformation.In recent years,a large number of studies have reported the discovery of face centered cubic titanium in titanium and titanium alloy after cold rolling,compression,tension,ball milling and so on.The preparation methods,phase transformation mechanism and deformation behavior of face centered cubic titanium in recent decades are introduced.The results indicate that face centered cubic titanium can greatly improve the strength of materials and improve the mechanical properties without sacrificing plasticity.
