Abstract
A double-stage mode of accelerated controlled hardening of large forgings from structural steels with relatively low hardenability in a water-air mixture with subsequent high-temperature tempering is described. Special features of the decomposition of supercooled austenite in these steels under continuous cooling are considered. The structure and properties of forgings after hardening by the recommended regime are studied.
