Cover Story: MD simulations were employed to study the He effects on generation and growth of cracks in nanocrystalline BCC-Fe in this paper. The relationship between the change of microstructure and the degradation of mechanical property during loading is discussed and analyzed. We conclude that the introduction of He in GB region is a fatal factor for degradation of tensile property in nanocrystalline BCC-Fe comparing with that in BCC region. The change of lattice constant and the atomic volume during loading should contribute to understand the degradation of mechanical property in the nanocrystalline models. View this paper
