Under shock loading, the plastic flow of polycrystalline material tends to localise into shear bands. As shear bands form, most materials dramatically lose their strain hardening property and quickly fail. Here, we present the experimental and microstructural evidence of a new shear banding mode–ductile shear band, in magnesium alloy at high temperature under shock loading. The results show that magnesium alloy could exhibit high strength and good plasticity even after ductile shear bands occurred and contributes to improve understanding of the strain rate‐dependent of failure modes in magnesium alloy.
