Peculiarities of dissociated dislocations cross sliding processes in cubic face-centered crystals
Abstract:
The dissociated dislocation cross sliding processes simulation in faced centered cubic crystals was carried out. The analysis was lead by molecular dynamics methods. Physical system parameters corresponded to aluminum and cooper crystals. Regularities of perfect dislocation dissociation characteristics influence on the energetic and dynamics of cross sliding process were received and analyzed. It was established that in aluminum crystals the width of stacking fault between partial dislocations corresponds to the value of perfect dislocation Burgers vector meanwhile the level of the cross sliding process energy barrier is about 1 eV; in cooper crystals the width of stacking fault by order of magnitude greater the value of perfect dislocation Burgers vector meanwhile the level of the cross sliding process energy barrier is about 5 eV.
