Abstract: Zr_<65>Al_<10>Ni_<10>Cu_<15> metallic glass ribbons prepared by melt-spinning were deformed in tensile at various strain rates between 5x10^<-4>s^<-1> and 1.7x10-<-1>s-<-1> in supercooled liquid region (673K). The microstructure of the ribbons after deformation was observed using high resolution transmission electron microscope (HRTEM). As a result, it was found that a high-strain-rate superplasticity of the metallicglass was caused by good deformability of the supercooled liquid state, and that an amorphous structure was preserved during the high-strain-rate deformation to failure.
