  Binary compounds in the Ge–Ti system

  摘要：

  The thermodynamic stabilities for the intermetallic compounds in the Ge-Ti system were studied using metallography, powder x-ray diffraction, and electron probe microanalysis. It was found that TiGe is not stable at 700 and 900 degrees C, and Ti3Ge is not stable at 700 and 800 degrees C. The other three compounds TiGe2, Ti6Ge5, and Ti5Ge3 are stable. A diffusion couple study between Ti and Ge was also performed at 800 degrees C for 105 h. It was found that only Ti6Ge5 and TiGe2 formed, but Ti5Ge3 did not. From the diffusion couple, it was found that Ti6Ge5 is not a line compound, but has an estimated homogeneity range from 42 at.% to 47 at.% Ge. (C) 1999 Elsevier Science S.A. All rights reserved.

  We have measured the resistivity as a function of temperature, rho(T), of superconducting Ti-1-x(Sn,Ge)(x) (0.03 less than or similar to x less than or similar to 0.12 for Ti-Sn and 0.03 less than or similar to x less than or similar to 0.07 for Ti-Ge) alloys below 25 K. These alloys are chosen because, upon dilute alloying, their impurity resistivities rho(0) vary readily from approximate to 55 to approximate to 150 mu Omega cm, while their superconducting transition temperatures T-c increase moderately by a factor similar to 60%. We find that the overall behavior of rho(T) can be quantitatively interpreted in terms of the Boltzmann transport AT(n) (with A being a constant and n an exponent) plus a temperature-dependent contribution Delta rho(I) arising from electron-electron interaction effects in the presence of disorder. Particularly, we observe a disorder dependence of Delta rho(I) similar to rho(0)(5/2). We also observe that the screened Coulomb interaction parameter (F) over tilde, defined in the electron-electron interaction theory, becomes much more negative in samples with increasing T-c.
