    摘要： The present invention discloses a method for improving mechanical properties by changing a gradient nanotwinned structure of metallic materials, and belongs to the technical field of nanostructured metallic materials. The method uses the inherent principles of microstructure and mechanical properties of metallic materials to improve materials mechanical properties. The metallic materials has a gradient nanotwinned structure. The principles of microstructure and mechanical properties of the metallic materials mean that the mechanical properties of the metallic materials are adjusted by changing the structural gradient scale of the nanotwinned structure. The method combines two strengthening methods of nanotwins and gradient structure, and can obviously improve the mechanical properties of the metallic materials. For pure copper materials of the gradient nanotwinned structure prepared by an electrodeposition technology: the yield strength is 481±15 MPa, the tensile strength is 520±12 MPa, the uniform elongation can be 7±0.5%, and the elongation to failure can be 11.7±1.3 %.

    摘要： A system for monitoring anodes that enables the automatic processing of the reconditioning of the anodes that have been used in electrolytic tanks. By monitoring the evolution of the anode and the possible deterioration thereof, it enables the relationship of the anode with the electrolytic process to be studied, and in this way carry out improvements in the electrochemical method, and the conditioning of the anodes to be optimized.
