Microstructure, texture, and fracture of pure magnesium adiabatic shear band under high strain rate compression

In the paper, the microstructure and texture of adiabatic shear band (ASB) in hat-shaped pure magnesium specimens under dynamic shear loading were investigated, and the formation and fracture mechanism of ASB were discussed as well. Results showed that, the straight ASB, with a width about 90 μm was formed upon shear loading, being consisted of the transition and ASB central regions. Equiaxed grains with large angle grain boundaries (LAGBs) were...
