摘要

In the regions of the deformed cube-on-edge single crystal of the Fe-3%Si-0.5%Cu alloy with an enhanced density of deformation twins, the nucleation of new grains during primary recrystallization (PR) occurs via several mechanisms. The majority of nuclei of PR are formed on twins as on substrates. The newly formed grains of PR are characterized by the presence of a cube-on-edge texture and are in special misorientations of the Σ3 type with respect to the twin orientation and of the Σ9 (Σ27) type with respect to the octahedral matrix. The mechanism of the formation of nucleation centers for PR on the twins as on substrates can be a splitting of the nonequilibrium special boundary Σ3. A significant role of special misorientations in the formation of the Goss texture upon PR has been shown experimentally.
