Numerical multi-scale simulations of the mechanical behavior of β-metastable titanium alloysTi5553 andTi 17
Résumé
The purpose of this study is to investigate the deformation mechanisms in the β-metastable titanium alloys Ti17 and Ti5553, which exhibit an important fraction of β phase (not, vert, similar 40%). A mean field model is introduced to depict the effect of microstructure onmechanical properties. The average behavior of each phase is taken into account : the micromechanical model simulates for each phase the respective elastic anisotropy and thevisco-plastic flow with kinematic and isotropic hardening. A good agreement has been obtained between numerical simulations andexperiments for several microstructures
