　　The dynamic properties of an ultrafine-grained(UFG)Fe and an intercritically annealed 0.2C5Mn steel with UFG austenite-ferrite duplex structure were studied under dynamic shear loading.The formation and evolution mechanisms of adiabatic shear band(ASB)were then investigated using interrupted experiments at different shear displacements and the subsequent microstructure observations.The evolutions of ASB in both materials were found to be a two-stage process,namely an initiation stage followed by a thickening stage.
