The use of mechanical alloying in the manufacture of .

Mechanical alloying, a high energy ball milling technique, was used to process elemental metal powders. Multifilamentary Cu-Nb3Sn composites were formed by mixing the mechanically alloyed Nb/Sn powders with Cu powders, isostatically compacting the mixture, hydrostatically extruding to wire form, and diffusion reacting to form the A15 superconducting compounds from the mechanically alloyed ...
