In the present in vestigation，with the help of the basic theory of stereology and quantitative metallogra-phy and analysis platform of quantification image soft-ware，a rigorous and available model of quantification of microstructural features was developed. Previously，the phase volume fraction was measured using area meth-od，and the mean intercept method was employed tome asure the grain and colony size. Based on the con-ventional methods mentioned above， a novel approachthat measuring the mean thickness of a laths in colonyusing Boolean operation is proposed in this work，which is shown in Figure 1. The feature parameters of micro-structures in titanium alloys extracted using this meth-od include phase volume fraction，grain size，thickness of Widmanstatten a laths， colony scale size， thickness and orientation of a phase. It not only reduces the errorwhich is associated with the lineation by users but alsoenhances the reliability of measured data. Moreover，inorder to unify the measurement standard of a phase in the basket weave，mixed and equiaxed microstructures of typical titanium alloys and take the continuity andsimplicity of quantification into consider ation，the eval-uated parameter of Feret Ratio was referred to present the evolution of c， phase and modeling the correlation of process，microstructure and mechanical property of ti-tanium alloys. The orientation of a phase was presentedby the angle to the primary axis of a phase and its ver-tical direction，which suggests that the characterizationmodel of evolution and orientation behavior in a phaseduring hot deformation of titanium alloys has been es-tablished，as shown in Figure 2. It should be noted that the proposed model has been successfully applied toquantitatively exhibit the dynamic evolution of a phase in TC17 titanium alloy with lamellar microstructure.Hence，the realization of quantification characterization about the evolution of lamellar a phase takes place of the traditional method that whether the globularizationphenomenon occurred. ……
