| Abstract Scope |
Unalloyed wrought Mg deforms primarily by basal slip and twinning which results in asymmetric deformation, strong basal textures and reduced ductility and formability. Fortunately, alloying can moderate these limitations, however predictive alloy design is limited by the lack of complete understanding of important mechanisms and lack of shared data! This talk will review work conducted by members of the PRISMS Center in the development and use of an integrated computational and experimental framework for investigating alloying effects on twinning and slip in wrought Mg alloys. A central component of the PRISMS framework is a suite of high performance, open-source multi-scale computational tools for predicting microstructural evolution and mechanical behavior. Using this software coupled with advanced experiments, including in-situ EBSD and 3D XRD we have quantified alloying effects on twinning and the propensity for pyramidal slip. Our data is shared with the community via the Materials Commons. |
