Classification of the Critical Resolved Shear Stress in the HCP materials by atomic simulation: Application to alpha-zirconium and alpha- titanium

Résumé

The Embedded Atom Method (EAM) approach has been applied to the study of five principle gliding systems in zirconium and titanium materials. The stacking fault energy maps are obtained and compared to the results of ab initio calculations. A good agreement was observed between the two approaches. Furthermore, the Critical Resolved Shear Stresses (CRSS) have been determined by Molecular Dynamics (MD) simulations based on the EAM potentials. The CRSS in the "a" direction for the basal, prismatic (type 1) and pyramidal (type 2) planes are obtained and compared.
