摘要：

The microstructure of the layers produced by plasma nitriding austenitic stainless steel at different treatment temperatures (400 and 500 degreesC) were studied by transmission electron microscopy (TEM) together with X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the microstructures were composed of 'expanded austenite' (gamma (N)) and or(ferrite) + CrN following plasma nitriding at lower and higher treatment temperatures, respectively. The former contains stacking faults and deformed twin substructures, while the latter is made up of colonies displaying a lamellar structure. Kurdjumov-Sachs or Nishiyama-Wassermann orientation relationships between the ct and CrN layer were observed. (C) 2000 Elsevier Science S.A. All rights reserved.
