Grain boundary elimination by twinning and dislocation nucleation in front of intergranular crack tips in BCC iron

Grain boundary structures with high resistance to intergranular fracture are the target of grain boundary design. In this work, grain boundary elimination in front of crack tip is observed in two special bcc iron bicrystals through molecular dynamics simulations under mode I loading. Grain boundary...
