The structures and fracture morphology of Mg61Cu20.3Ag8.7Er10 amorphous alloy were analyzed using XRD and SEM.The mechanical behaviors of Mg61Cu20.3Ag8.7Er10 amorphous alloy were investigated under different temperatures and strain rates.The results show that at room temperature,the fracture strength of the amorphous alloy is decreased with the increase of strain rate.When the temperature at-100 ℃,the amorphous alloy exhibits high strength as well as certain plasticity,The strain rates have little effects on the strength and plasticity of amorphous alloy.
