Abstract

Nitrogen addition to iron alloys improves mechanical properties. The composition of the alloy as well as the melt pressure influences nitrogen concentration. In this US Bureau of Mines study, nitrogen concentrations in Fe-Cr-Mn alloys were determined. New thermodynamic expressions were derived to relate nitrogen concentration to alloy composition and melt pressure. These expressions included nonlinear terms, such as pressure-concentration and Cr-Mn terms.
