On the Occurence and Intensity of the Work-Softening of Steels

CIM Bulletin, 1962

The rate of work-hardening is shown to govern the occurrence of the work-softening phenomenon, in agreement with the prediction of N. H. Polakowski. There is some evidence that the effect of austenite stabilizing elements on the intensity of the phenomenon may be explained by their indirect influence on the rate of work-hardening. Straining a work-softened specimen after ageing causes the phenomenon to reappear. This may be explained by the rearrangement during deformation of the system of microscopic internal stresses resulting from strain ageing.
