Origin of abnormal formation of pearlite in medium-carbon steel under nonequilibrium conditions of heating

详细

The structure and kinetics of the formation of austenite in medium-carbon steel during shortterm heating above the temperature Ac₁ followed by accelerated cooling are analyzed. It has been shown that the abnormal formation of pearlite in steel results from the concentrational and structural inhomogeneity of austenite, as well as the presence of carbide particles in ferrite areas.
