“…The retained austenite can have beneficial effects on the corrosion resistance, because it favors chromium and molybdenum carbonitrides dissolution, increasing the content of these elements in the matrix. According to Bilmes et al 21 the pitting corrosion mechanism can also be associated with crack propagation, in which cracks propagate from the martensite phase to the austenite phase, ductile and stable, making them difficult to spread. Thus, the higher austenite volume fraction in tempered conditions, the lower pitting susceptibility 5,22 .…”

“…부식으로 인한 경제적 손실과 안전재해 사고를 유발 할 수 있 으므로 강의 용접부식에 대한 연구 결과 (Bilmes et al, 2006;Jeon, 1985;Jones, 1998;Lee et al, 2003;Moon et al, 2003;Raja et al, 1998;Tsay et al, 1997) (4) 표면의 조직이 미세할수록 내식성은 양호한 경향을 나타내었다.…”

“…Esse efeito produz um aumento da tenacidade desses aços (Toussaint & Dufrane, 2002). O efeito dessa austenita, na resistência à corrosão, é polêmico e, ainda, não foi esclarecido (Kimura et al, 2001;Bilmes et al, 2006 A diminuição da resistência à corrosão, após o tratamento térmico de revenido, é atribuída à precipitação de carbonetos ricos em cromo nos contornos de grão e entre as ripas de martensita. A formação desses carbonetos provoca o empobrecimento de cromo na matriz adjacente (Truman, 1976).…”
