摘要：

Fe-Cr powdered alloys synthesized via mechanical attrition have been examined by magnetization and Fe-57 Mossbauer spectroscopy. Mossbauer studies reveal that Fe1-xCrx becomes paramagnetic for x greater than or equal to 0.46 after 100 h milling. Magnetization results suggest that a significant reduction of Fe magnetic moment occurs in the nano-crystalline Fe1-xCrx alloys. Curie temperature for x = 0.46 and 0.69 lies below liquid N-2 and liquid He temperature, respectively.
