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

Influence of Pulsed Magnetic Field on the Al-Heterodiffusion in α-Fe

“…The highest variations of the DC of Al and the dislocation density [7] are observed when annealing of the samples in the PMF with the intensity amplitude ranging from 0 to 80 kA/m. It is reasonable to assume that this results from the fact that under these conditions the state of the saturated magnetization of the samples is not yet achieved.…”

“…A sufficiently complete description of the procedure of measurements is given in [6,7]. In the present paper only its basic details are cited.…”

“…The information on the PMF effect on the diffusion and diffusion-controlled processes in solids is rather poor. Other authors [6,7] have indicated for the first time that the frequency and amplitude of the PMF intensity within the interval of 0,2-8 Hz influence the diffusion coefficient (DC) of Al in Fe at the temperature of 730 °C; and assumptions on possible mechanisms of this effect are advanced.…”

Effect of Pulsed Magnetic Field on Spark Plasma Sintering of Iron-Based Powders

“…Consequently, the SPSing of powders can be improved by coupling a superposed variable magnetic field. Moreover, following M. A. Verzhakovskaya et al, 13) an external pulsed magnetic field affects the diffusion coefficient of alloying elements and the dislocation density in iron during conventional sintering, when the sintering temperature is slightly less than Curie point. Application of a pulsed magnetic field leads to magnetization reversal to the sample, which is accompanied by a change in the period of domain walls and their shift.…”

A study on the room-temperature magnetoplastic effect of silicon and its mechanism

“…Magnetoplastic effects firstly reported in 1987 [1] originally referred to the phenomena that a magnetic field affects the dislocation-controlled plasticity of solids including ionic [1][2][3][4][5][6][7][8], covalent [6,[9][10][11][12][13][14][15][16][17][18][19][20] and metallic [3,4,[21][22][23][24][25][26] crystals. With the deepening of the relevant researches, a variety of effects of magnetic field on the microstructures [27][28][29][30][31][32][33][34][35][36] and properties [34,[36][37][38][39][40][41][42][43]…”
