    Abstract

    This study reports the plasticity improvement of amorphous alloy associated with skim cold rolling. It was found that, with an increasing reduction in thickness of up to 6 %, the plastic strain increased considerably from 1.5 % to 9.6% while the yield strength deceased slightly from 1.75 GPa to 1.68 GPa. With further rolling beyond 6 %, the changes in the plasticity and yield strength were observed to be insignificant. In this study, we discussed the principle underlying the improved plasticity of amorphous alloy in view of the creation of excess free volume during skim cold rolling.
