Abstract The microstructure features of abnormal microstructure during transformation from austenite and the hardness of specimens heat treated at different cooling rates (1, 2 and 5℃/min) without and with applying a magnetic field (12 T) in the Fe-1.1%C alloy were investigated. The results showed that the area percentage of abnormal microstructure in the specimen heat treated under magnetic field decreases with the cooling rate increasing. The reason is that the diffusion is limited with the cooling rate increasing. At the same cooling rate, the area percentage of abnormal microstructure in the specimen heat treated with magnetic field is more than that in the specimen heat treated without magnetic field and the hardness of the specimen heat treated with magnetic field is lower.
