【Abstract】 The Argon single atom indentation processes is analyzed using molecular dynamics simulation technique. The effects of substrate temperature and indentation speed on the interfacial normal force, material deformation behavior is revealed. The direction of the dislocation movement is shown to coincide with that of macroscopic plastic flow. The compressive yield strength decreases with increasing substrate temperature and decreasing indentation speed.更多还原
