Fe-Cr powdered alloys synthesized via mechanical attrition have been examined by magnetization and /sup 57/Fe Mossbauer spectroscopy. Mossbauer studies reveal that Fe/sub 1-x/Cr/sub x/ becomes paramagnetic for x/spl ges/0.46 after 100 h milling. Magnetization results suggest that a significant reduction of Fe magnetic moment occurs in the nano-crystalline Fe/sub 1-x/Cr/sub x/ alloys. Curie temperature for x=0.46 and 0.69 lies below liquid N/sub 2/ and liquid He temperature, respectively.
