Abstract

Polycrystalline aggregate models are built based on the theory of Voronoi diagram, then crystal plasticity finite element method (CPFEM) is used to study the relationship of microstructures and stress-strain responses in Ti-6Al-4V alloy during uniaxial tensile tests at room temperature. Stress–strain responses of the Ti-6Al-4V alloy were investigated at different strain rate to study the deformation behavior. Based on the model, the effects of grain size, volume fraction of globular primary p-phase and strain rate on stress-strain responses are investigated. Results indicate that compared with strain rate and volume fraction of primary p-phase, grain size show a significant influence on stress-strain responses, the stress has a tendency of increase with the grain refinement. The strain distribution range of aggregates increases with increasing of the strain rate, the stress decreases with increasing of the volume fraction of primary p-phase.
