Abstract: The problem of establishing the correlation between, on the one hand, the chemical and phase compositions of Ni$_{(1-x)}$W$_{x}$ alloys (0 $\le x \le$ 0.5) and, on the other hand, the character of the temperature dependences of the electrical resistivity, is considered. Based on the experimental $\rho(T)$ curves, the concentration dependences of are reconstructed in the wide temperature range (50 K $\le T \le$ 273 K). The $\rho(x)$ curves have features related to a change in the crystal structures of the alloys (concentration fcc–bcc phase transition), their magnetic structures and percolation processes occurring in the two-phase fcc + bcc medium.
