A dislocation dynamics study of the strength of stacking fault tetrahedra. Part II: interactions with mixed and edge dislocations

Abstract

In this paper we present the sequel to Part I and present a comprehensive dislocation dynamics study of the strength of stacking fault tetrahedra to mixed and edge dislocation glides in fcc Cu.

Keywords:

• dislocation dynamics
• irradiation damage
• stacking-fault tetrahedron
• mechanical properties
• Cu
