The stability of supercooled austenite in various types of steels was studied under accelerated cycled cooling conditions. The Cr--Ni-- Mo steel was found to be most stable while the Cr-- W--Si steel exhibited the least amount of stability. Cycled accelerated annealing, including supercooling to 220 deg C, ensured a more complete decomposition of the supercooled austenite; a single cycle with an extended soaking step at 650 deg stabilized the austenite. The precision of the measurements depends greatly on the standards employed. Unneeded, long soaking periods for several tens of hours at 200 to 300 and at 640 to 660 deg C, used for forging, usually results in a reduction of the quality of the steel as it increases the strength of the residual austenite.
