Magnesium is a lightweight structural metal and has important applications. However, the dislocation plasticity of magnesium was not well studied, especially the pyramidal dislocations. In this paper, molecular dynamics (MD) simulations were performed to systematically investigate the dislocation interactions, i.e. between dislocations, between dislocations, between and dislocations, as well as between and dislocations. Various new interaction products were observed and analyzed. The current work provides new insights into the dislocation plasticity for understanding the mechanical property of magnesium and its alloys.
