  Cu${}_{50-x}$Zr${}_{x}$ (x = 50, 54, 60 and 66.6) polycrystalline alloys were
prepared by arc-melting. The crystal structure of the ingots has been examined
by X-ray diffraction. Non-equilibrium martensitic phases with monoclinic
structure were detected in all the alloys except Cu${}_{33.4}$Zr${}_{66.6}$.
Temperature dependencies of electrical resistivity in the temperature range of
T = 4 - 300 K have been measured as well as room temperature values of Hall
coefficients and thermal conductivity. Electrical resistivity demonstrates
anomalous behavior. At the temperatures lower than 20 K, their temperature
dependencies are non-monotonous with pronounced minima. At elevated
temperatures they have sufficiently non-linear character which cannot be
described within framework of the standard Bloch--Gr\"{u}neisen model. We
propose generalized Bloch--Gr\"{u}neisen model with variable Debye temperature
which describes experimental resistivity dependencies with high accuracy. We
found that both the electrical resistivity and the Hall coefficients reveal
metallic-type conductivity in the Cu-Zr alloys. The estimated values of both
the charge carrier mobility and the phonon contribution to thermal and electric
conductivity indicate the strong lattice defects and structure disorder.
