Effect of a pulsed magnetic field on the diffusion of aluminum in iron and the fine-structure parameters of iron

The effect of a pulsed magnetic field with a strength in the range 0–557.2 kA m^?1 and a frequency in the range 0–8 Hz at a temperature of 730°C on the diffusion of aluminum in iron, the microhardness of iron, and the dislocation density in iron has been experimentally investigated by metallography and X-ray diffraction. It is established that a pulsed magnetic field significantly affects the diffusion coefficient of aluminum and the dislocation density in iron. Possible mechanisms of the influence of a pulsed magnetic field on the characteristics measured are discussed.
