摘要：

A mechanical alloying process for a mixture of elemental Fe and Cr powders with the Cr compositions 20-70 at. % was investigated through the measurements of x-ray diffraction, magnetization, and Fe-57 Mossbauer spectrum. We show that magnetic studies provide more detailed information about the alloying process occurring during ball milling than the conventional diffraction techniques in this particular system. A final product after ball milling was identified as a high-temperature phase of the alpha solid solution, regardless of compositions studied. Powders subjected to milling in Ar gas atmosphere for 200 h were further ball milled in N2 atmosphere. The presence of N2 gas has caused a partial amorphization. The amorphous phase thus produced is found to be paramagnetic at room temperature.
