| Mechanical alloying method was used to obtain Co40Fe40Ni20 alloy from the elementalpowders. X-ray diffraction studies revealed that the final product of milling was the solid solutionwith b.c.c. lattice and the average grain size of about 36 nm. After heating of the alloy up to 993 Kthe mixture of two solid solutions with b.c.c. and f.c.c. lattices with small amount of the third iron-oxide phase was formed. Annealing of the alloy at 1173K during 1 h resulted in the formation of thesolid solution with f.c.c. lattice. Mössbauer spectroscopy allowed to determine the hyperfine inter-actions parameters of the obtained phases. Results of the macroscopic magnetic measurementstestified that Co40Fe40Ni20 alloy had relatively good soft magnetic properties |
