Formation and annihilation of stressed deformation twins in magnesium

Load partitioning to grains during deformation of a polycrystalline material is affected by the presence of twins. Here, synchrotron diffraction is used to study 1300 twin-parent grains, revealing that stress is higher in twins than in the parent grain during the early stages of plastic deformation.
