Milling and mechanical alloying of copper and some ...

1994-12-1  During the milling of elemental copper or mixtures based on copper an intense cold worked structure is built up which leads to orientation dependent internal strains and an isotropic internal stress. The extent of this retained stress varies with alloying as the stacking fault energy changes and the rate of stress relaxation is altered.
