| Abstract Scope |
Interface sliding though not generally reported in <α/β> titanium alloys has been shown to be a governing deformation mechanism at room temperature in the alloy Ti-407 in this study. In-situ straining in the SEM has shown that sliding occurs at the beginning of plasticity, with increasing propensity until fracture. TEM has revealed that a-type prismatic slip at early stages of plasticity is responsible for the activation of sliding thus generating large strain-gradients leading to the generation of a high density of additional slip events adjacent to the sliding interfaces, determined using high-resolution EBSD and confirmed with TEM. Poor alignment of slip systems between neighboring colonies, and thus lack of slip transfer, is found to initiate extensive sliding causing increased ductility. It is speculated that the interface sliding is controlled by the strength of the <α> phase and may be the reason this phenomenon is seen only in certain alloys. |
