摘要：

The influence of a magnetic field on the motion of twin dislocations is studied to understand the mechanism involved in magnetically driven shape memory alloys. Application of magnetic field imposed high values of stress. However, in the cases where strong dislocation pinning occurs, or where grains boundaries act as barriers to dislocation motion, the influence of the magnetic field on the shape memory effect can be substantially diminished.
