Abstract
Formation and propagation of crack in quenching+tempering(QT) and quenching+ intercritical quenching+ tempering (QLT) treated Fe-9%Ni-C alloys were investigated by means of in-situ scanning electron microscope (SEM) and transmission electron microscopy (TEM).The sample treated by QLT showed better cryogenic toughness than QT treatment. High content of retained and reversed austenite in QLT-treated alloy could be tested which located not only on the high angle grain boundaries such as prior austenite boundary and packet boundary but also within the laths which was stable during loading because of protection of harder phase. Retained and reversed austenite in QT treated alloy mainly located at high angle grain boundaries and was weak in stability during loading, could not improve cryogenic toughness of the alloy comparatively.
