Abstract Magnesium is a lightweight structural metal but the industrial application is limited by its poor intrinsic
ductility. Pyramidal dislocations are believed to be responsible for the ductility enhancement whereas
the dislocation plasticity of magnesium was not well studied, especially the pyramidal dislocations. In this
work, molecular dynamics simulations were performed to investigate the pyramidal disloation behaviors
including the decomposition of pyramidal dislocations on both pyramidal-I and pyramidal-II planes and the
interactions between themselves and other dislocations in Mg. The pyramidal-I dislocations are
decomposed into and dislocations under shear stress at 0-400K, which all reside… More >
