Abstract: The compression deformation and fracture behaviors of Zr41.25Ti13.75Ni10Cu12.5Be22.5 bulk metallic glass with low ratio of height to diameter have been studied by means of Instron Univeral-Testing Machine (IUTM) and scanning electron microscopy (SEM) at room temperature.The elastic deformation was dominated by plastic deformation before fracture.Work hardening was found during the plastic deformation and fracture stress reached 2 031 MPa.The macrocopic morphology of the cylinder samples with low ratio of height to diameter shows the formation of three kinds of fracture surfaces along 0°,39°-43° and 90° angle with respect to the loading direction,respectively.The fracture surfaces were formed by shear mode,which included shear,longitudinal and horizontal splitting.The diversity of deformation and fracture of the samples of the bulk metallic glass with low ratio of height to diameter under compression condition reaulted from complex stress fields.
