Summary

Isothermal and non-isothermal bend stress and anelastic strain relaxation of melt spun ribbons of the Al7.5Cu17.5Ni10Zr65 bulk metallic glass was studied at 4 constant temperatures and 6 constant heating rates using a Perkin Elmer DSC 2 as a heat treatment equipment [1], and the theoretical approach described in [1, 2], respectively. It has been shown that the bend stress relaxation and the fully irreversible strain contribution due to viscous flow only, can be successfully described in accordance with the Free Volume Model (FVM) concepts with a common set of physically meaningful FVM parameters. The experimental techniques used provides the possibility to separate quantitatively the fully reversible anelastic strain contribution from the fully irreversible viscous flow strain contribution. It has been shown, that the experimentally determined anelastic strain contribution can be described on the basis of the Kohlrausch–Williams-Watts stretched exponent equation.
