摘要： A method of rolling NiW alloy tapes for coated conductors belongs to the technical field of metal materials rolling. According to the method, a cylindrical NiW alloy ingot with a diameter not less than 10 mm is used to be rolled back and forth along the axial direction as a rolling direction, wherein the content of W is 5˜7 at. %, and the axis of this ingot is perpendicular to the plane where the axes of working rollers are located. During rolling process, the cross sectional area reduction of the ingot is retained at 5% per pass. When the total cross sectional area reduction of the ingot is larger than 98% and the thickness of the tape is down to 60˜100 μm, the rolling is stopped, and thus the NiW alloy tape is obtained. The method has the advantages that the negative influence generated when the NiW alloy tape is produced from a cuboid initial NiW alloy ingot can be reduced as much as possible, the yield of the NiW alloy tapes is increased, as well as relatively ideal effects can be obtained in terms of the surface biaxial texture, the length and the axial quality.
