Abstract At room temperature Fe and Cu form almost no solid solution in equilibriumphase diagram but X-ray diffraction and DTA show that the metastableFe_(1-x)Cu_x supersaturated solid solution can be obtained after 5 h of ball-milling of the mixedFe and Cu powders. The bcc phase is extended over the region with x≤0.10, while the fccphase with x≥0.30. For 0.10
