The paper gives details of the research carried out on the low temperature properties of Mo-Re alloys in the superconducting and normal states. Measurements were made on a variety of Mo-Re alloys in various states of anneal, the alloys being in the form of fine wires, as suitable for the winding of high-field superconducting solenoids. Micrograph studies were made to determine the percentage of the various phases present in each specimen. The low temperature measurements covered observations on the various specimens of the electrical resistivity as a function of temperature and of magnetic field and the thermal conductivity also as a function of temperature and magnetic field. The measurements yielded evaluations of two of the three critical magnetic fields, H sub c2 and H sub c3 as a function of temperature and alloy constitution, the transition temperatures T sub c and the Landau-Ginsburg parameter k. Detailed comparisons of the results are made with theoretical predictions and with results by previous authors on similar high-field superconducting alloys. Author
