Abstract
New copper–tungsten (W–Cu) composite wires are developed for the winding of non-destructive pulsed magnets. A micrometric Cu powder coated with a nanometric layer of W (1.8 vol%) was used as the starting material. W is chosen for its very high shear modulus, and its introduction at the nanometric scale aims to avoid co-deformation incompatibilities during wire drawing. Composite cylinders were fabricated by cold spraying and then deformed by wire drawing at room temperature, allowing the fabrication of wires.Keywords
