Abstract
Twinning of bismuth crystals under a concentrated load is found to be partly suppressed by a constant magnetic field. The main mechanisms of the influence of a constant homogeneous magnetic field on the twinning of bismuth single crystals subjected to long-term concentrated loading is studied. It is revealed that the length and the number of wedge twins at an indentation decrease in the magnetic field. This suggests a decrease in the mobility of partial twinning dislocations and in the intensity of the nucleation of wedge twin interlayers in a constant magnetic field. Application of the magnetic field increases the width of twins at the mouth. No anisotropy of the magnetoplastic effect is observed upon twinning.
