Abstract

It is shown that the experimental data on the temperature dependences of the effective electrical resistance and thermal conductivity in the range of 4.2–300 K of the electroconsolidated Fe0.5Ni0.5 composite are within the Hashin–Shtrikman boundaries for the conductivities of a three-phase system. The components of the system are pure Fe and Ni, and the intergranular medium in the form of an alloy with an average composition close to Fe0.5Ni0.5 is considered as the third phase.

Key words: electroconsolidated composite, electrical resistance, thermal conductivity, Hashin–Shtrikman boundaries, three-phase system, intergranular medium.
