Abstract Large hardness increases were recently reported for an ASTM A723 steel and a tool steel when a 1 kVcm−1 external electric field was applied during the post-austenitization quench. The increased hardness was attributed to a field-induced order-of-magnitude decrease in the austenite decomposition rate during the quench. The results of an extensive study of austenite decomposition kinetics in the same A723 steel and a similar tool steel in the presence and absence of electric fields of magnitudes up to 3 kVcm−1 during post-austenitization cooling are reported here. Differential thermal analysis and thermomagnetic analysis were employed to directly monitor the austenite decomposition processes in both steels. Supplementary hardness measurements in the tool steel are also reported. No effects of external electric fields on austenite transformations were detected.
