Temperature dependence of impurity resistivity in dilute Al-based Ti, V, Fe, Cu, Zn alloys between 78 and 930 K

The temperature dependence of the impurity resistivity of dilute Al–Ti, Al–V, Al–Fe Al–Cu, Al–Zn was measured between 78 and 930 K. The determination of the temperature dependence of dϱ/dT was carried out by using directly the slopes of the R(T) curves. The impurity resistivity was found to be independent of temperature within the experimental error, only very small differences were observed near the melting point of Al.
