Effects of cold work on silver-rich silver-magnesium solid solution alloys

Abstract

The stored energy of cold work and the electrical resistivity of silver-rich silver—magnesium solid solution alloys were measured as functions of true strain, magnesium concentration and the initial state of order. The results were analysed on the assumption that the measured property changes caused by cold work reflect additive changes due to increases in the dislocation density and to the reduction of order. Explicit expressions are given for these components of the stored energy and the resistivity increment. For the alloys with long-range order, property changes due to reduction of order predominate. For the alloys with short-range order, the dislocation density was calculated as a function of magnesium concentration, from the stored energy and the resistivity increment data; the two sets of values of the dislocation density are in fair agreement. For a given strain, the dislocation density increases with magnesium concentration rapidly at first and then tends to level off in concentrated solid solutions. © 1969 Taylor & Francis Group, LLC.
