摘要：
The present study concerns magnetic behavior of nanocrystalline Cu-Ni, Cu-Fe and Cu-Ni-Fe alloys prepared by mechanical alloying. It has been found that the magnetic properties e.g. H-c, M-r and M-s of the nanocrystalline alloys were significantly influenced by the changes in microstructural constituents, grain size and evolution of phases. Microstructural changes in the alloys have been effected by carrying out isothermal treatments on the mechanically alloyed products in the temperature range of 450-650 degrees C. Phase evolution in the samples after the isothermal treatments were identified and characterized by X-ray diffraction (XRD) and differential scanning calorimetric (DSC) techniques and the results were correlated with the magnetic properties of the alloys.
