Abstract A dislocation model of a shear band appearing in an amorphous material subjected to plastic deformation is proposed. On the basis of this model, analytical expressions for the components of the stress near the shear band are obtained. The behavior of the stress state near the shear band is considered. The distribution of impurities near the shear band in an amorphous material is calculated. It is established that the impurity is localized away from the shear band, rather than near to it. This is accounted for by a specific configuration of the long-range stress fields. An increase in temperature leads to a decrease in the concentration of the impurity in the place of its maximum density. The influence of the stresses in the shear band on the formation of various phases in it is studied.
