| Co(40)Fe(50)Ni(10) and Co(50)Fe(45)Ni(5) ternary alloys were prepared by mechanical alloying method. To check the stability of their structure thermal treatment was applied subsequently. As X-ray diffraction studies proved the final products of milling were the solid solutions with bcc lattice and the average grain sizes ranged of tens of nanometers. After heating of the Co(50)Fe(45)Ni(5) alloy up to 993 K the mixture of two solid solutions with bcc and fcc lattices was formed. In other cases thermal treatment did not change the type of the crystalline lattice. Mossbauer spectroscopy revealed hyperfine magnetic field distributions which reflected the different possible atomic surroundings of (57)Fe isotopes. Results of the macroscopic magnetic measurements proved that both investigated alloys had relatively good soft magnetic properties. |
