boundariesconsisting of dislocation arrays were detected in the recovered slugs. Some twins andslip dislocations were observed in specimen deformed at normal strain rate. It wasfound that dynamic recovery and recrystallization take place during high-strain-ratedeformation due to the temperature rising, whereas the conventional slip mechanismoperates during deformation at normal strain rate. Key words......
and a slanting slip zone along [1,0,1] are captured under the indenter.The generation and evolution of V shape dislocation in the slanting slip zone are analyzed via the centrosymmetry parameter, and the motion... dislocation to perfect dislocation leads to multiple jumps in friction force. The strain contribution analysis shows that the proportion of dislocation slip is finally about 10%, while twinning migration......
