Microstructure of the Heat Treated Advanced Low Carbon Steel

Abstract:

The microstructure of the advanced low carbon steel with a superior hardenability was studied. The steel contained the following main alloying elements, wt. %: C – 0.20; Cr – 2.0; Mn – 2.0; Si – 1.04 Ni – 1.0; Mo – 0.3. The dilatometer investigation of the steel under consideration revealed the only phase transformation occurring during continuous cooling (0.1...30 °C/s), which started at the martensite start temperature M_s. It was shown that the isothermal treatment of the studied steel led to the bainite formation above and below M_s. The temperature of the bainite morphology shift was determined.
