This work focuses on integrating various computational models in order to understand microstructure and texture development in Ti-5Al-5V-5Mo-3Cr, which is a near beta alloy, used in aircraft components. A viscoplastic self-consistent (VPSC) model is used to understand the deformation behavior of the material. Parameters of the mechanical threshold stress (MTS) hardening law are optimized using a least-squares approach to match the experimental stress-strain response at different temperatures and strain rates. The model predictions are compared with various reported studies for other Titanium alloys, similar in composition to Ti-5553.
In order to study the micromechanical response, representative 3D microstructures have been created based on experimental Electron Backscatter Diffraction (EBSD) data. The deformation behavior of the synthetic microstructures is studied using crystal plasticity Fast Fourier transform (CPFFT) codes using the optimized MTS parameters.
