Abstract: | This paper reports {sup 57}Fe Moessbauer spectroscopic studies of the polycrystalline samples of the substitutionally disordered, isostructural (fcc), ternary alloy system Fe{sub 80-x}Ni{sub x}Cr{sub 20} for x = 30, 26, 19 and 14 in the temperature range of 10-295 K. The data have been analyzed in terms of the magnetic phase transitions occurring in these alloys by examining the temperature dependence of the various Moessbauer parameters like line-width, center shift, resonance area, distribution of hyperfine field, P(H), and the average hyperfine field <H>. An estimate of the magnetic transition temperature T{sub C} is made for the alloys with x = 30 and 26 and these results are compared with those previously obtained by magnetic measurements and neutron diffraction experiments. The data for the second order Doppler shift have been analyzed to estimate the Debye temperature {theta}D for alloys with x = 30 and 26. |
