The diffusivities and effective charge numbers were determined by using resistivity techniques at temperatures of between 310 and 480K. The addition of Cr or Ti was found to decrease both the diffusivity (figures 38 and 39) and the charge number at all temperatures. The alloys exhibited higher activation energies for diffusion than did pure V. In every sample, and for both isotopes, the charge number decreased with increasing temperature. The charge number was larger for D than for H.
