摘要：
Metastable omega phase in near-beta titanium alloys is helpful for the precipitation of fine alpha precipitates, which can affect mechanical properties of these alloys. Therefore, researchers have studied the formation conditions, classification, transformation mechanism and diffraction patterns of the omega phase since it has been found. This paper summarized the recent research results on embryonic omega, composition of omega and effects on alpha phase, which were researched by high resolution transmission electron microscopy and three-dimensional atom probe. On this basis, this paper expounded the current research difficulties and possible development direction.
