Dynamic mechanical response and microstructural evolution of extruded Mg AZ31B plate over a wide range of strain rates

In this research, the mechanical behaviors of extruded AZ31B Mg plate along normal direction (ND) were investigated over a wide range of strain rates. High strain rate tests were carried out using a split Hopkinson pressure bar at room temperature. The corresponding deformation mechanisms, texture e...
