Mechanical behavior of Dy3Al2 metallic glass at room temperature and different strain rates was investigated. Enhanced microscopic ductility was observed at the highest strain rate tested of 10-1 s-1 when multiple parallel shear bands on the gage and fracture surfaces were observed. Possible differences in deformation process by tension and compression were discussed.
