Studies on electrical conductivity
Abstract
The law of Matthiessen and Vogt makes it possible to bring together two classes of alloys. Both represent mixtures, the first - substances that correspond in their properties to the temperature of observation, the second - substances that seem to be heated to a higher temperature, and therefore have slightly different properties, but can be predicted, since this fictitious higher temperature determines the meaning and magnitude of the changes they could undergo. This can be confirmed to a certain extent by the effect of annealing on the electrical conductivity of alloys, for example, a perfectly studied pair of silver and copper. Before annealing, alloys have greater resistance—being first in a hardened state.
