- Аннотация: A 50Fe + 25Al + 25Si powder mixture was mechanically alloyed in a high-energy ball mill, and the products of the solid-state reactions were characterized by x-ray diffraction and magnetic measurements. The results show that the process involves the formation of a metastable bcc Fe〈Al,Si〉 solid solution, which decomposes into the ordered phases FeAl 1-x,Si x (B2 structure) and FeSi (B20) upon heating to 700°C or long-term milling. The observed effect of milling on the magnetic properties of the powders indicates that the proportion of the ferromagnetic component in the alloy decreases with increasing milling time as a result of the ordering of the solid solution and the formation of the B2 and B20 paramagnetic phases. © 2001 MAIK "Nauka/lnterperiodica".
