【Abstract】 Mechanisms of localized shear deformation and fracture in amorphous alloys are summarized based on free volume model,adiabatic shear model,dislocation model and mechanics model.A new model of "free volume+adiabatic heating" is proposed and applied to explain the deformation and fracture behavior of amorphous alloys.Furthermore,some problems and new directions in the aforementioned field are discussed briefly.更多还原
