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.
