Abstract The ω phase and its phase transformation in titanium alloys have great influence on the microstructure and properties of the alloys. Therefore, the study of ω phase transformation in titanium alloys becomes one of the hot issues in recent years. In this paper, the related research reports are summarized, including ω phase formation, ω phase decomposition, ω phase morphology and ω -assisted α nucleation. The advantages and disadvantages of the related models are compared, and some scientific problems with academic disputations are expounded.
