摘要：
Dynamic material modeling (DMM) analysis has been employed to examine the high strain, elevated temperature mechanical behaviour of Widmanstatten alpha(2) + beta Ti-26Al-10Nb-3V-1Mo. Flow regimes predicted by this analysis were then correlated with microstructural observations. Unstable now zones were associated with alpha(2) platelets kinking and shear band formation in the alpha(2) + beta-phase field, with now localization at grain boundaries and dynamic grain growth in the beta-phase field. Stable flow was associated with dynamic spheroidization of the Widmanstatten alpha(2) platelets in the alpha(2) + beta-phase field, and with dynamic recrystallization in the beta-phase field.
