Mechanical alloying of Si and Ge in a planetary ball mill
Aug 10, 1994 Fe, Ni and Cr elemental powders have been ball milled in a planetary mill for various periods of time, up to 27 h. XRD analysis allowed the determination of the structure of the mixture, the average crystallite size and the lattice parameter as a function of milling time. The complete formation of FeNiCr is observed after 27 h milling.A cost comparison Production and smelting of prereduced.
