1.Carbon, chromium, and nickel promote an increase in strength and a reduction in ductility and impact strength for cast carburizing steel after quenching from a temperature of the intercritical range. Manganese and silicon have a negative effect on these properties.2.Multiple regression analysis made it possible to optimize the composition of cast carburizing steels and to establish production limits for the content of elements providing the required values of strength, ductility, impact strength, hardenability, and carburizability.3.A method for mathematical planning of the experiment was used to optimize the repeated-quenching temperature and final low-temperature tempering temperature in order to obtain the required properties for the core of carburized articles made of steel 18KhGNMFL. Strength properties and relative elongation of this steel depend on both temperatures, but relative reduction of area and impact strength only depend on the repeated-quenching temperature. |
