Etudes on electrical conductivity
Abstract
The law of Matthiessen and Vogt makes it possible to bring together two classes of alloys. Both represent mixtures, the former are substances that correspond in their properties to the temperature of observation, the latter are substances that appear to have been heated to a higher temperature, and therefore possess somewhat different properties, yet these properties can be predicted, since this fictitious higher temperature determines the meaning and magnitude of the changes they may have undergone. This can be confirmed to a certain extent by the effect of annealing on the electrical conductivity of alloys, for example, the thoroughly studied pair of silver and copper. Before annealing, alloys exhibit greater resistance, being initially in the hardened state.
