Abstract
The nitrogen solubility in liquid Fe–Cr alloys has been measured by the gas–liquid metal equilibration technique in the temperature range from 1873 to 1973 K. The nitrogen dissolution follows the Siverts' law for liquid Fe–Cr alloys containing chromium up to 30 mass%. Chromium increased the nitrogen solubility linearly at Cr content less than 3 mass%, and the second-order effect of Cr on nitrogen solubility was apparent at higher Cr content. Using Wagner's formalism, the first- and second-order interaction parameters between chromium and nitrogen were determined from the equilibrium relation between chromium and nitrogen contents in liquid Fe–Cr–N alloys as a function of temperature:[Equation]
