USE OF THERMOKINETIC DIAGRAMS OF DECOMPOSITION OF SUPERCOOLED AUSTENITE FOR DESIGNING THE PROCESS OF HARDENING OF STEEL PARTS AT A VARIABLE COOLING RATE

摘要

A method for computing the nonequilibrium process of hardening of steel parts at a variable cooling rate, which is based on thermokinetic diagrams (TKD) of decomposition of supercooled austenite, is suggested. The dependences of the intensity of the hardening process on the temperature make it possible to determine the time of the start of the structural transformation and to design its further occurrence.
