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 ...

ball milling of nb3sn

In the present paper we demonstrate disordering during ball-milling of two intermetallic com- pounds, namely Nb3Sn and CoGa. Nb3Sn crystal- lizes in the A15 structure and exhibits anti-site disorder under irradiation, resulting in an increase of the lattice parameter and a decrease of the superconducting transition temperature T~ [2].

ball milling of nb3sn

A novel Nb3Sn superconducting jointing method by means of powder metallurgy was presented to reduce the resistance for purpose of satisfactory magnetic field stability of high field NMR instrument. In this research, Nb, Sn and Cu element powders were introduced in ball milling processing to prepare the (Cu, Sn) solid-solution before pressing and sintering.
