Abstract

Los aceros inoxidables austeníticos JK2, JJ1 y JN1 se envejecieron isotérmicamente a temperaturas de 600 a 900 ºC por distintos tiempos, para estudiar la evolución microestructural y su efecto en la tenacidad a la fractura a temperaturas criogénicas. La energía de fractura Charpy muesca-V a 77 K muestra una significante disminución con el tiempo de envejecido en los aceros JJ1 y JN1 debido a sus altos contenidos de C y N. Las fractografias de MEB de las muestras ensayadas por CMV muestran fractura frágil cuya fracción aumenta con el tiempo y temperatura de envejecido.
