Title
Phase transformation in Fe - Cr - Ni alloys at low temperature aging
김동훈 Tong Hoon Kim
Abstract
The aging effect of Fe-Cr-Ni alloys at around 475℃ embrittlement temperature has been studied by means of electron microscopy. The modurated structure was found to be very similar to the theoretical pattern of the spinodal decomposition. The embrittlement phenomena of this ternary alloy seams to the spinodal decomposition separated into two phase of iron-rich and chromium-rich solid solution with consideration of the spectrum of Mo¨ssbauer effect, the microstructure changes by potentiostatic etching, microhardness observation and the electron microscopic study.
