%X mechanical alloying (ma) is a powder processing technique, which allows us to induce solid state reactions in binary systems immiscible in equilibrium. fe and ag have a mutually repulsive nature that makes them completely immiscible under thermodynamically stable conditions. the ball milling process being a non-equilibrium technique seems promising in obtaining at least a partial solid solution in this system. mixtures of fe and ag powders with 75 wt% ag were studied by x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). we have found that it is possible to obtain a small mutual solid solution in this system by ma. this is also confirmed by m£¿ssbauer spectroscopy.
