| Abstract Scope |
Understanding how alloying affects twinning in magnesium alloys is key to expanding their use as lightweight structural materials. The PRISMS Center at the University of Michigan is addressing this by developing open-source modeling software and a data repository called Materials Commons, in addition to conducting advanced experiments to accelerate research. This talk highlights progress in measuring grain average resolved shear stresses during twin nucleation and growth in Mg-1wt.%Y using High Energy X-Ray Diffraction Microscopy (HEDM). Prior to experiments at the FAST beamline at CHESS, simulation tools (MechVDE and PRISMS-Plasticity, developed at CHESS and PRISMS center, respectively) were used to inform the far-field detector distance, target HKLs and expected differences in detector attenuation needed to successfully capture the twinned grains. The project also emphasizes developing best practices for recording and sharing metadata for both the simulated and experimental HEDM studies, ensuring reusability and accessibility through Materials Commons. |
