Abstract: The lattice parameters, crystallite size and strain of nanostructured Cu1-xFex (0< x <0.5) alloys prepared by the ball milling method were determined from X-ray powder diffraction analysis. All samples present the Cu fee structure. The lattice parameters of the Cu 1-xFex phases increase with x. Furthermore, they are significantly greater than the values predicted by Vegard's law. The X- ray diffraction peaks were analyzed using the Warren-Averbach and Integral Breadth methods. The crystallite size decreases and the strain increases with Fe concentration. A high degree of anisotropy was observed in both the apparent crystal size and strains. Possible inhomogeneities in the fee phase cannot be discarded.
