Nitrogen Solubility in Liquid Fe–C Alloys

Temperature Dependence of the Solubility of Nitrogen in Liquid Silicon Equilibrated with Silicon Nitride

The solubility of nitrogen in liquid silicon equilibrated with silicon nitride and its dependence on the composition of the atmosphere has been studied in the temperature region 1428–1542 C. High purity silicon was melted in silicon nitride crucibles under Ar and N2 atmospheres. The equilibrium was observed to be established within minutes, after which no evolution of the nitrogen content with ...

Semiempirical Theory of Solid Solubility in Transition Metal Alloys

A semiempirical theory of solid solubility in transition metal alloys is presented. The theory is based on writing the energy of formation of the solid solution as a sum of several contributions: a) a chemical contribution due to electronic redistribution in forming the alloy, b) an elastic contribution arising from the difference in size between solute and solvent atoms and c) a structural con...

Calculation of solubility in titanium alloys from first principles

We present an approach to calculate the atomic bulk solubility in binary alloys based on the statistical-thermodynamic theory of dilute lattice gas. The model considers all the appropriate ground states of the alloy and results in a simple Arrhenius-type temperature dependence determined by a ‘‘low-solubility formation enthalpy”. This quantity, directly obtainable from first principles, is defi...
