dc.description.abstract | Ammonia-gas nitriding of AISI 304 austenitic stainless steel was studied at temperatures higher than 800 degrees C using SEM and X-ray diffraction. The result showed that S-phase, an expanded austenite, was formed even at such high temperatures due to a high nitriding potential of ammonia gas. The equilibrium phase, CrN was formed through a decomposition of S-layer in two different modes; the one was through continuous precipitation of particles at the surface-side of S-layer due to a higher nitriding potential; the other through a discontinuous(-like) precipitation at the austenite interface-side, producing a. ne lamellar structure of austenite and CrN. The gamma-phase in the surface-side resulting from the precipitation of CrN particles subsequently transformed into Fe(4)N because of a fast enrichment of N atoms and a limited mobility of Cr atoms at the surface-side. A coarse lamellar structure made of austenite and Cr(2)N was developed in front of. ne lamellae composed of austenite and CrN by the decomposition of supersaturated austenite through a discontinuous precipitation via grain boundary movement.
