The influence of impact shock-loading was investigated on the mechanical behaviour,
microstructure evolution, and texture of a new high-Mn steel. The mechanical behaviour of the
shock-loaded specimen was compared with quasi-static compression condition. A Hopkinson
pressure bar setup was used to perform the high-strain-rate deformation. Continuous yielding
was observed under both low and high-strain-rate deformation. The yield stress also illustrated
a positive strain-rate sensitivity with increasing strain-rate. An obvious increase in the flow stress
of the steel was detected at higher strain-rate. A strain hardening followed by a strain softening
was detected in stress–strain curve after shock-loading. Electron backscatter diffraction
also displayed the activation of strain-induced.
