Changes in structural and magnetic properties during mechanical alloying and heat treatment were studied in Cu0.8(Fe1−xCox)0.2 (x=0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6) alloys using x-ray diffractometry, transmission electron microscopy, and magnetometry. Supersaturated solid solutions with a fcc crystal structure were obtained in all alloys by mechanical alloying. The grain sizes of the solid solutions were about 20 nm. Magnetization of the supersaturated solid solutions could be explained by a mixture of two types of particles showing paramagnetism and ferromagnetism. The variation in magnetization with Co content in the solutions was similar to the Slater–Pauling curve. Fe–Co with a bcc structure precipitates during annealing of the Cu0.8Fe0.1Co0.1 alloy. With increasing annealing temperature ferromagnetic behavior becomes dominant due to a coarsening of the precipitates. © 1996 American Institute of Physics.
