It is shown that the Mo – 47% Re – 0.4% Zr alloy after rolling deformation (ε ≈ 90%) at room temperature exhibits certain characteristic features, such as increased density of deformation defects with considerably faceted noncoherent boundaries and reorientation microbands with a specific range of high-angle disorientations around the direction of the 〈110〉 type. Using the concepts on direct-plus-reverse (along alternative systems) martensitic transformations as the mechanisms of plastic deformation and crystal-lattice reorientation, an analysis of possible mechanisms for formation of these states is made.
