Abstract
A thermogravimetric analysis has been applied to processes in R6M5 hig h-speed steel powder thermochemically treated in ammonia. Temperature ranges have been identified for the adsorption of nitrogen, nitriding, and denitriding. To prepare a powder containing nitrogen of superequi librium concentration, conditions have been defined for maximum nitrog en uptake, fullest appliance of phase transitions, and diffusion. isot hermal hold at 520 degrees C for 20 min and at 620 degrees C for 60 mi n.
