An apparatus for measuring the electrical resistivity of materials from 4.2K up to 273.2K was constructed and used to test niobium zirconium alloys of the following compositions: Nb + 15% Zr, Nb + 25% Zr, Nb + 33% Zr, and Nb + 50% Zr. It was found that the temperature dependence of the electrical resistivity in these alloys is approximately linear, with Matthiessen's Rule holding for the lower concentrations. The residual electrical resistivity is shown to depend linearly on zirconium concentration.
