Influence of Pulsed Magnetic Field on the Al-Heterodiffusion in α-Fe
Based on the X-ray method an experimental research has been carried out aimed to estimate the pulsed magnetic field influence on the heterodiffusion of Al in -Fe within the temperature interval of 700-820 °С and at the amplitude intensity of the magnetic field pulse equal to 0–557.2 kА/m and its frequency ranging from 0 to 8 Hz. It is established that the pulsed magnetic field changes noticeably the value of the measured coefficient of Al diffusion in -Fe. Possible mechanisms of the pulsed magnetic field influence on the diffusion process are considered on taking into account the interaction of moving domain walls, dislocations and impurity atoms.
