摘要：
The electrical resistivity (ρ) of Ni-base alloys containing Fe up to 30 at% has been measured in the temperature range from 4.2 to 1600 K. The concentration dependence of residual resistivity in Ni-Fe alloys, which received the atomic ordering, furnace-cooling and water-quenching heat-treatments, suggests the formation of the Ll2-type superlattice at Fe concentrations higher than 14 at%. The Curie temperature, which was determined as the inflection temperature in the ρ-T curves, agrees well with that determined by the previous magnetization measurements. The correlation between the magnetic resistivity and the ferromagnetic properties is discussed from the viewpoint of the scattering process of conduction electrons due to the localized-spin disorder. © 1990, The Japan Institute of Metals.
