摘要：

Fe60Ni40 metastable alloy was fabricated by the mechanical alloying process. The magnetization of the processed powder decreased gradually as the alloying time increased. The formation of the alloy was confirmed by the structural analysis. X-ray diffraction analysis showed that the long range order was remained until 6h but disappeared after 12h of milling. EXAFS showed that there was a substantial change in the local structure between 6 and 12 h of milling. The structural analysis showed that alloying was activated in 6 h and completed almost in 24 h. The estimated bond distance of Fe-M (M: Fe or Ni) for the final alloy was about (2.54 +/- 0.02) angstrom.
