    Abstract Poor ductility heavily limits the industrial application of magnesium (Mg) alloys, and pyramidal dislocations are an important deformation mode for ductility enhancement. In this work, discrete dislocation dynamics (DDD) simulations were performed to study the mechanical behavior and dislocation evolution of Mg singlecrystals compressed along c-axis. Especially, basal-transition and cross-slip algorithms of pyramidal dislocations were proposed and introduced in the DDD method. Simulation results show that basaltransition is an important mechanism for the strong strain hardening observed during c-axis compression of Mg single-crystals. Since the basal-transition events are thermally activated, increasing temperature leads to a More >
