Effects of martensite cold work on the reverse austenite formation

Ricardo Vilain de Melo, Carlos Augusto Silva de Oliveira and Cássio Aurélio Suski

Abstract

The effects of martensite cold work on the reverse austenite formation were analyzed using vibrating sample magnetometry. The samples were previously austenitized at 820°C for 30 min and then subjected to 85% height reduction. In sequence, the samples were aged at 600°C for different periods of time. For comparison purposes a set of non-deformed samples – labelled as 0% deformation – was submitted to the same aging conditions. The mechanical deformation initially retarded the reverse austenite formation in the matrix.
