Notes:
A series of AM60B, die-cast magnesium alloy specimens have been examined using xraytomography at spatial resolutions from 1 – 20μm and further characterized in uniaxial tension.This paper first reports the utility of a critical strain model to link the local area fraction of porosityand the fracture strain. A discussion of the trade-off between predictive accuracy and the spatialresolution of the imaging technique is also presented in order to address the technologicalimplications of these results. In the second half of the paper, serial tomographic imaging is used toillustrate the evolution of damage with increasing uniaxial strain. The implications are discussedwith respect to numerical modeling of the performance of die-cast magnesium components
