Abstract
The electrical resistivity rho and its temperature and concentration derivatives d rho /dT, d rho /dc and d2 rho /dTdc are reviewed and measured for Cu substitutionally alloyed with Ti. The CuTi samples are prepared by a conventional method with heat-treatments as well as by melt-spinning. Heat-treatments are found to deplete the Cu matrix of Ti. From the values of d rho /dT the authors conclude that the electron-phonon interaction remains almost constant when Cu is alloyed with Ti. FCC CuTi is therefore non-superconducting.
