... temperature range to form ferrite-austenite mixtures. This is followed by accelerated cooling (6 °C/s, or 10 °F/s) to transform the ferrite-austenite mixtures into ferrite-martensite mixtures ( Fig. 4 ). The actual cooling rate depends on sheet thickness and the quenching conditions on a given annealing line...
