    Abstract: Compared to its mechanical behavior at 298 K, the fracture strain of a Cu(46)Zr(46)Al(8) bulk-metallic glass is slightly increased, but the maximum strength is distinctly increased by 13.3% at 77 K. At 77 K, the serrations in the stress strain curve disappear. Based on the calculation of the temperature rise within the shear bands and the heat conduction in the heat-affected zones, the large and instantaneous temperature rise and the rapid heat conduction are responsible for the disappearance of serrations upon shear banding.
