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.
