Nanogranulation process into magneto-resistant Co–Cu alloy on the route of bulk mechanical alloying

Abstract

Nanogranulation process is investigated on the route of our developed bulk mechanical alloying. Cu–Co binary system is employed to describe the alloying process from the elemental powder mixes into the homogenized solid solution and to understand the nano-sized precipitation of Co from the homogenized solid solution in the copper matrix for various annealing conditions. Size and morphology control of Co-particulate in the nanometer order in this nanogranulation process has close relationship with the materials design of magneto-resistance and magnetic anisotropy in the nanogranular system. Various experimental validation is necessary to construct the nanomechanical methodology as a theoretical model to describe intrinsic properties to nanogranular materials.
