The annealing of iron-chromium alloys containing more than 40 percent chromium at 600°C, and above where the so called 475°C brittleness is not observed, causes the shift of the magnetic transformation temperature to a somewhat higher temperature. In order to clarify this phenomenon, the measurement of thermomagnetic behavior, hardness, thermal expansion, and magnetization-curves and observatioms of microscopic structures were made on iron-chromium alloys heat treated in several ways. It is known that this phenomenon is not due in the formation of the FeCr superlattice but is explained by the precipitation and resolution of chromium compounds such as chromium carbide.
