摘要：
Deformation and crack initiation of industrial Ti-6Al-4V titanium alloy sheet were investigated using in-situ scanning electron microscopy (SEM) at room temperature. The results showed that slip band originated from alpha/alpha and alpha/beta interfaces when the tension reaches the yield stage, and the slip mode develops from single slip to multi slip and finally the cross-slip occurs. Microcracks initiate primarily at the phase boundary or along the slip band within alpha phase, cracks are mainly connected along the 45 degrees line. The fracture surface is full of dimples. Intergranular cracking is the main fracture mechanism. (C) 2018 Elsevier B.V. All rights reserved.
