Abstract Scope |
Deformation twinning is a mechanism of critical interest in magnesium as it allows for the accommodation of strain, but can also create preferential fracture pathways. This issue is amplified by instances of twin transmission, where a twin impinges on a grain boundary and nucleates a new twin in the neighboring grain due to the stresses associated with the intense local shear. Most commercial Mg alloys are multi-phase, featuring micron-scale particles located along the grain boundaries that can create potential barriers for the stresses generated by impingement of the twin tip. A combined computational and experimental approach is utilized to examine how the characteristics of these grain boundary particles can modify twin transmission behavior in commercial Mg alloys. |
