High pressure melting was used to increase the nitrogen concentration in iron-carbon alloys. Nitrogen concentration in the alloys followed Sieverts' Law. Increasing the carbon concentration decreased the nitrogen concentration. Alloy concentrations above approximately 0.5wto/o nitrogen and carbon resulted in stabilizing the austenitic phase and eliminated the formation of nitrides and carbides.
