The mechanical alloying process continually deforms, cold welds, and breaks apart metal powder particles. During the process of mechanical alloying elemental crystalline powders can produce an amorphous alloyed powder. Consolidation of these powders

The diffusion and electrotransport properties of iron in α and β scandium were measured over the temperature range 970 to 1515 °C. The diffusion coefficients are of the order of 10−9 to 10−10 m2 s−1 in both phases. The effective valence Z
