Abstract: Changes in the orientation and substructure of crystallites in metals were studied during the migration of grain boundaries in the recrystallization process. It is determined that the changes are caused by a significant moving force of recrystallization and the presence of inhomogeneities in the structure of metals. These inhomogeneities, having the structure and properties different from the basic metal, form a substantial contribution to the moving force of recrystallization.

Abstract: A new way of considerable improvement of properties of soft magnetic alloys is offered. This way actually consists in the use of an ion beam treatment in the manufacturing technology for these alloys. Depending on the properties, which need improvement (magnetic softness or magnetostriction), the ion beam treatment is performed before or after a thermomagnetic treatment.

Abstract: A new concept is suggested that serves to explain the effects of thermomagnetic treatment. Its validity is proved via measurements of magnetic properties and electron microscopy examination of structure of soft magnetic materials after different treatments. This concept allows one to consciously choose the treatment mode aiming on improvement of magnetic properties of alloys.
