Failure mechanism and mode of Ti-6Al-4V alloy under uniaxial tensile loading: Experiments and micromechanical modeling

The failure of dual-phase alloys under tensile loading conditions is often due to the nucleation, growth and coalescence of voids at the interface between different phases from micromechanical point of view. The aim of this paper is to identify the failure mechanism and mode of dual-phase Ti-6Al-4V alloy in the form of plastic strain localization due to the incompatible deformation between the softer α phase and the harder β phase under the...
