Abstract

Magnesium deforms via twins that form in a grain then expand both forward and laterally, causing local stresses that have yet to be measured. Here, the authors measure the full strain and stress tensors around a twin in a bulk polycrystal and show that the twinning grain deforms heterogeneously.
