Abstract: The deformation behavior of the Zr 69.5Cu 12Ni 11Al 7.5 bulk metallic glass (BMG) was examined by compression, tension and three-point bending test. It was found that the BMG exhibits excellent room temperature plasticity and toughness with a compressive strain over 11.5%, a tension strain of about 0.2-0.3% and a notch toughness of 86 ± 5.5 MPa m 1/2. Structural analyses revealed that the existence of strong icosahedral medium-range order (IMRO) clusters in amorphous phase, which contributes to the good plasticity and toughness of the BMG studied.
