Stress overshoot in stress-strain curves of Zr65Al10Ni10Cu15 metallic glass

The essential features of the stress overshoot in the stress-strain curves of ${\mathrm{Zr}}_{\mathrm{65}}{\mathrm{Al}}_{\mathrm{10}}{\mathrm{Ni}}_{\mathrm{10}}{\mathrm{Cu}}_{\mathrm{15}}$ (at. %) metallic glass that has a wide supercooled liquid region were revealed. The stress overshoot was dependent on temperature, strain rate, and stress relaxation. During the stretch, a change in strain rate gave rise to stress overshoot or undershoot which was sensitive to the variable quantities in the strain rate.
