Small-angle neutron scattering study of the magnetoplastic effect in the beryllium bronze aged in magnetic fields

Kinetics of aging of the Cu-Be alloy with different beryllium concentrations in an external constant magnetic field

“…As seen from Figs. 2a-2c, the switching on magnetic field increases the transmission that indicates on a decrease in the fraction of nanosized clusters of the scale of the neutron wavelength and an increase of the fraction of coarse scale clusters and phases with the substantially larger size (to ~1000 Å) [3].…”

“…The transmission is understood to be the intensity of a direct neutron beam passed through the sample with no scattering measured by the central detector. The measurement of the transmission allows one to obtain information on neutron scattering by phases various in scale formed during artificial annealing including the phase formations commensurate in size with the neu tron wavelength and, as shown in [3], to analyze the influence of magnetic field on the processes of phase formation.…”

“…In [1][2][3], the effect of magnetic field on the pro cesses of aging in a commercial berillium bronze BrB 2 alloy was detected. The effect is in a significant (to 30%) increase in the alloy microhardness during its aging in a dc magnetic field, and also in a change in the neutron transmission during switching on-switch ing off magnetic field.…”

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]…”
