A method for plotting thermokinetic and isothermal diagrams of decomposition of supercooled austenite in powder porous steels with the help of a high-accuracy magnetometer is suggested. Thermokinetic and isothermal diagrams of decomposition of supercooled austenite in hot-formed powder steel PK40N2M are analyzed.
