Stress Relaxation in Coiled Ribbons of Fe40Ni40P14B6 and Fe29Ni49P14B6Si2.

Abstract

The stress relaxation at elevated temperatures in coiled ribbons of Fe-Ni base metallic glasses is calculated for both power law creep and Eyring activated flow. The results are compared with experimental data on the spring back of coiled ribbons after various anneals. Good agreement is obtained for Eyring activated flow, but not for power law creep. Comparison with stress relaxation experiments on straight sections indicates that stress relaxation in coiled ribbons is largely due to transient creep. (Author)
