Electrical resistivity measurements on binary Al-15 wt-%In alloy

Abstract

A rotational contactless inductive measurement technique has been used to determine the electrical resistivity of an Al-15In (wt-%) binary alloy over a wide range of temperatures. It is shown that the electrical resistivity depends on the distribution of the indium within the aluminium matrix. The results can be considered as a first attempt to detect the onset of the sedimentation process, which occurs in alloys of this type, by measuring the electrical conductivity of immiscible alloys.
