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 Matthiessens Rule holding for the lower concentrations. The residual electrical resistivity is shown to depend linearly on zirconium concentration. Author
