| Abstract Scope |
In this talk we will revisit the characteristics of <c+a> pyramidal slip in magnesium. In particular, literature over the past few years has been dominated by conflicting atomistic simulation results that in many cases directly conflict with experimental observations in terms of the lack of ductility at room temperature versus the transition to large ductility at elevated temperatures. To overcome these conflicting results in literature, here we revisit the predictions from atomistic simulations in view or recent experimental studies to develop a more proper understanding of <c+a> pyramidal slip in magnesium. In particular, the traditional view of plasticity being dominated by a single pure screw or pure edge dislocation does not hold for pyramidal slip. Instead a holistic view of the collective behavior of dislocations and the characteristics of mixed dislocation must be accounted for. |
