Abstract
The effect of a magnetic field on grain growth was studied in nanocrystalline samples of nickel and nickel-20mass% iron alloy produced by electrodeposition. It was found the application of a magnetic field restricts abnormal grain growth resulting in the formation of more homogeneous grain structure, while abnormal grain growth took place during ordinary annealing without a magnetic field. Abrupt grain growth took place at later stage of magnetic annealing but the grain structure with much larger grain size was still uniform. The DSC measurents during magnetic annealing revealed the appearance of a peak associated with grain growth in nanocrystalline pure nickel and nickel-20mass%iron alloy. It was found that the peak associated with grain growth was shifted to high temperature side by about 10K during magnetic annealing. This was ascribed to a decrease of the grain boundary energy under a magnetic field.
