Abstract

Mechanical deformation behaviors of Cu single crystal metal with two different surface orientations (Cu (100), Cu (110)) and two bi-crystal Cu metals (Cu(100)/Cu(110) and Cu (110)/Cu (100)) during a nanoindentation process are explored by molecular statics simulations. On two single crystal surfaces, our results indicate that the influence depth can be affected by the tip indentation and the motion of dislocation induced by the tip. For bi-crystal cases, the interfaces between the two crystal orientations can provide resistance to the motions of dislocation, strengthening the mechanical properties of the Cu material.
