Abstract
Electrical resistivity studies of a series of Ti‐V alloys have revealed anomalously large isothermal resistivities within the composition range 10−70 at .%V, and a negative resistivity temperature dependence within 20−33 at .%V. Alloys such as Ti−V exhibit electronically induced lattice instability which increases in severity as the electron/atom ratio dedreases, and which manifests itself as a 2/3<111≳ longitudinal lattice displacement wave, the source of the ω‐phase precipitation. Whether the negative resistivity temperature dependence were a result of scattering by phonons or by phonon‐induced reversible athermal precipitation was not obvious. Analysis of the results of magnetic susceptibility temperature dependence measurements on the same system, however, yielded a reversible component whose appearance and disappearance paralleled the resistivity result. It follows that the anomalous resistivity is, at least in part, of macroscopic origin.
