Atomic-scale simulation of α/γ-iron phase boundary affecting crack propagation using molecular dynamics method

We simulated the effect of K-S and N-W phase boundary on micro-crack propagation. Initial crack parallel to phase boundary is inclined to be integrated. K-S bi-phase system has higher ductile behavior than N-W one. Slip is able to traverse the K-S boundary along (0 1 -1)γ/(-1 1 1)α.
