HIGH-SPEED, BULK MECHANICAL ALLOYING OF CU AG/CO SYSTEMS/

Mixing and homogenization, refining and alloying processes in the bulk mechanical alloying by the repeated MA-forging are experimentally inv estigated to define the standard process condition. Through experiment al demonstration of the effect of each process parameter on the above fundamental processes, controllability of the related process paramete rs to this bulk MA is described towards productive mechanical alloying . The Ag-Cu, Cu-Co and Ag-Co systems are chosen as typical immiscible systems to discuss the intrinsic effect of constituent elements on the solid solubility in the alloying processes.
