摘要: The mechanisms of deformation at the crack tip in L12 Ni3Al have been studied by molecular dynamics simulations. stress-induced microtwinning is found to occur when a sufficiently high stress concentration exists. formation mechanism discussed. It be achieved emission Shockley partial dislocations from and then slip on adjacent {111} planes. Furthermore, also discussed standpoint stress.
