Abstract
In this study, high-pressure high-temperature diffusion at the US Bureau of Mines was used to increase the nitrogen concentration in both b.c.c.- and f.c.c.-iron alloy powders. Microstructures of the powders and precipitates were determined using microprobe, scanning electron microscopy (SEM)_and X-ray diffraction. Formation of Fe 4N was observed in Fe, Fe-1018, and Fe-2Al. For FeCr alloys, either b.c.c or f.c.c, the first precipitate to form was CrN. Experimental results compared favorably with computer generated phase diagrams and computer predictions from the Swedish Institute for Metals Research of nitrogen concentration and as a function oof diffusion pressures.
