Abstract
In this stuby, high-pressure high-temperature diffusion at the US Bureau of Mines was uses to increase the nitrogen concentration in both B.C.C.- and F.C.C.-iron alloy powders. Microstructures of the powders and precipitates were determines using microprobe, scanning electron microscopy (SEM) and X-ray diffraction. Formation of Fe4N was observed in Fe, Fe-1018, and Fe-2Al. For Fe-Cr alloys, either B.C.C. or F.C.C., the first precipitate to form was CrN. Experimental results compares favorably with computer generates phase diagrams and computer predictions from the Swedish Institute for Metals Research of nitrogen concentration and as a function of diffusion pressures
