摘要：
The subtransus deformation behaviour of Ti-10V-2Fe-3Al alloy was investigated. The flow stress curves are featured with significant flow softening, resulting from the breaking up and globularisation of lamellar alpha phase. The critical major axis of alpha phase to cause flow softening is 1 mu m. Alpha phase acts as a dislocation barrier in the beginning and suppresses the recrystallisation of beta matrix. Dynamic recovery is the main restoration mode for beta matrix and alpha phase just works as a marker of it. Beta phase is dominated by strong {001} and weak {111} orientations. The Burgers relationship and variant selection are observed between a phase and beta matrix in a single grain and overall samples, and the subtransus deformation does not destroy it.
