Abstract

The temperature and concentration dependences of electric resistivity of nickel-chromium alloys in liquid state have been studied. Experimental data shows non-linear concentration dependence of rho isotherms of alloys. The wavy-type character of the isotherms of nickel-chromium melts resistance has been qualitatively explained with the theory of percolation and model of microunhomogeneity structure of melts.
