“…Hardening is given by the nitrogen diffusion into the crystal lattice. Although the mechanism of diffusion of nitrogen in austenitic stainless steels (ASS) has been extensively studied [6][7][8] . In the case of DSS there are studies where nitrided layer properties are evaluated 5,9,10 , but the mechanism of formation and the morphology of the layer have not been deeply studied 11,12 .…”

“…Entretanto o processo de nitretação não pode ser realizado em temperaturas superiores a 550ºC, devido à intensa precipitação de nitretos complexos de cromo na zona de difusão (Venkatesan et al, 1997, Larisch et al, 1999, Czerwiec et al, 2000, Liang et al, 2000. A precipitação dos nitretos eleva a dureza, mas diminui, sensivelmente, a resistência à corrosão desses aços.…”

“…A literatura descreve essa fase como sendo uma solução sólida supersaturada de nitrogênio na austenita metaestável. De acordo com os autores Menthe e Rie (1999), Pranevicius et al (2001), Picard et al (2001) e Fossati et al (2006, essa fase encontra-se livre de nitretos, com reticulado cristalino CFC altamente expandido, conduzindo a um elevado estado de tensões residuais de compressão na camada nitretada, sendo denominada de "Fase-S" ou "Austenita Expandida - N ". A expansão volumétrica no reticulado CFC, associada à supersaturação em nitrogênio, é observada pelo deslocamento dos picos de difração de raios X para a esquerda, para menores ângulos 2, e pelo seu alargamento.…”

“…The expanded austenite is a layer rich in nitrogen, obtained in austenitic stainless steels like the AISI 304 after nitriding in temperature of 500 ∘ C. Structural analyses show that the modified layer is dominated by a cubic phase with a substantial expansion of the austenite lattice and in some cases a fine layer (<0.1 m) of CrN and -Fe precipitates at the surface. The lattice parameters show that the expanded austenite could be described by a special triclinic crystalline structure [14][15][16][17][18].…”
