Abstract Stress relaxation measurements have been performed at room temperature on the metallic glass Fe67Co18B14Si1. A negative stress relaxation, which appears to be intrinsically irreversible has been observed above a critical stress. The result is compared with results obtained from anelasticity measurements on as-cast and stress-relaxed specimens. The hypothesis that the effect observed is connected with mechanically induced annealing mainly linked to internal stress healing is discussed.
