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 ...
متن کاملOxygen Solubility in Liquid Iron and Consequences for the Early Differentiation of Earth and Mars
Introduction: It has been considered that the Earth accreted from carbonaceous chondrite-like material (e.g., [1], [2]). This hypothesis is based on the observation that the refractory element ratios of Earth’s mantle are close to carbonaceous chondrite values, although the ratio of metallic Fe to total Fe is much closer to that of enstatite chondrite (e.g., [3]). Recently, Halliday [4] suggest...
متن کاملResearch Perspectives in the Field of Acoustic Treatment of Liquid Alloys of Iron
K. Nowacki, Silesian University of Technology, Department of Metallurgy, Katowice, Poland One of significant factors affecting properties of steel is uniform distribution of non-metallic inclusions and alloy elements across the steel product cross-section. Acoustic treatment may be the final technological stage enabling the quality of steel to be influenced. Further research to be undertaken in...
متن کاملEvaluation of Nitrogen Diffusion in Plasma Nitrided Iron by Various
Diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (OM), microhardness depth profiling (HDP), scanning electron microscopy (SEM), x-ray diffraction (XRD), glow discharge optical emission spectroscopy (GDOES), and secondary ion mass spectroscopy (SIMS). Plasma ni...
متن کاملSemiempirical 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...
