The effects of plastic deformation upon the microstructure of alloy samples which had been deformed at various temperatures were examined. Changes in the susceptibility and spontaneous magnetization were measured as functions of strain, and were correlated with the development of the microstructure; as observed via high-voltage electron microscopy. Particular attention was directed to the formation of antiphase-boundary tubes by super-dislocation motion. Increases in the susceptibility and spontaneous magnetization were attributed to local changes in the ordering of D03 and B2 phases by super-dislocation motion. This was especially predominant at low temperatures; perhaps in the absence of dislocation climb.
