Abstract: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 alloys 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 alloys after cold rolling, compression, tension, ball milling and so on. Face centered cubic titanium can greatly improve the strength of materials and improve the mechanical properties without sacrificing plasticity, which has been widely concerned by scientific researchers. In this paper, the preparation methods, phase transformation mechanism and deformation behavior of face centered cubic titanium in recent decades are introduced.
