Development of rotational plasticity during deformation of Fe-1.5wt% Si alloy

The study of deformed Fe-1.5 wt% Si alloy, using mainly X-ray diffractometry methods, shows different stages in the development of plasticity, each of which has its own driving forces and structural elements. These stages are represented by conventional dislocation mechanisms or translational displacements and by disclination mechanisms or rotational displacements. After rolling, there are fewer opportunities for the rotational mechanism of plastic deformation than after a tensile test. This is due essentially to a more regular development of plastic flow in the material.
