The Martensitic Transformation in Pure Iron
Abstract
High-rate quenching experiments have established that iron containing less than 0.0017 percent degree C transforms martensitically at 750 degree C at cooling rates in excess of 35 000 degC/s. M(s) falls to 540 degree C, and the critical quenching speed is lowered to 5000 degC/s when the carbon content is increased to a figure between 0.005 and 0.01 percent. Two hypotheses are offered to rationalize the effect of carbon, and Crussard's shock-wave model of the martensitic transformation is extended.
