Abstract:
Results are given of experimental measurements of the electrical resistivity of commercial-grade titanium with a purity of $99.7\%$ by mass and of polycrystalline iodide titanium with a purity of $99.91\%$ by mass in the temperature range from $77$ to $1600$ K. At temperatures of $77$–$350$ K, the electrical resistivity of commercial-grade titanium is higher than that of iodide titanium; however, as the temperature increases, $\rho$ of commercial-grade titanium becomes lower than $\rho$ of pure titanium in the entire temperature range of the $\alpha$- and $\beta$-phases. The temperature range of inversion is $360$–$380$ K.
