Summary:

It has been shown in earlier chapters that during nonstationary nucleate boiling, a self-regulated thermal process occurs, where the surface temperature of a part to be quenched is kept above the saturation temperature. This provides an opportunity to greatly affect the martensite transformation process by either retarding or accelerating it. There are two methods available. The first is to use additional pressure to increase the boiling point of the boundary liquid layer. The second is to use high-concentration aqueous solutions of salts or alkalis where the saturation temperature is increased. The use of both approaches is effective when quenching high-carbon steels where the martensite start temperature MS is less than 200C (that is, MS<=200C)
