N2 - In this paper, using a software, prepared by the General Research Institute for Nonferrous Metals to analyze rotation field in materials deformation. By using this software, we analyzed the deformation rotation field in process of tensile for CuY0.8 nano-alloy strip and Nickel-based alloy, and analyzed performed on the rotation behavior, rotation extent and its character among the grains after the polycrystalline metal materials had been yield-deformed, and getting rotation field which is coming with the CuY0.8 nano-alloy strip and nickel-based alloy deformed. It was observed that after plastic deformation, the nano-crystalline grains and its neighborhood occurred a rotation-induced change, the rotation blocks presented on pairs wise as gears, its rotation was in the opposite direction, and in the rotation-pairs region the energy transfer was observed. In the poly-crystalline nickel-based alloy, after plastic deformation among the crystal grains the rotation-pairs occurred in many locations. It is proposed that plastic deformation shows more intensively, the grains rotation angle will is bigger, and in the macroscopic point of view, the generation of Lüders bands is closely related with rotation between grain blocks.
