| Abstract: | Conclusion Tungsten both with small and large amounts of supercooling increases austenite stability, but niobium with small amounts of supercooling (550–450°C) decreases it, and with large amounts (350°C and below) it increases its stability. On alloying chromium-nickel cast iron with cobalt austenite isothermal decomposition moves to the left, and alloying with boron accelerates the austenite decomposition process in the temperature range 550–500°C with an increase in its stability in the range 500–200°C.Dnepropetrovsk Metallurgical Institute.
