Effects of Mo, Ti and Zr on the Solubility of Carbon in Molten Iron

Studies on the behaviors of carbon in molten iron-II

Abstract

Measurements on the effects of molybdenum, titanium and zirconium on the solubility of carbon in molten iron were made and the periodicity of the interaction parameter with respect to the atomic number of the third element was confirmed to hold true for these elements.
Through the statistical-thermodynamical discussion, the physical meaning of the interaction parameter, its dependencies on temperature and carbon content and its relation to the free energy of formation of carbide were explained.
