Abstract

Ag-2. 2 at. percent Al specimens were internally oxidized at 773 K and 1173 K. At 1173 K, the resistivity decreases rapidly and attains a steady state value after 3. 6 ks. In contrast, the resistivity gradually increases on annealing at 773 K, and attains a gradually increases on annealing at 773 K, and attains a steady state value at some 100 ks. The increase in resistivity on low temperature oxidation and the decrease on high temperature oxidation is a common trend for specimens with different Al contents. One possible explanation for the resistivity increase is the formation of a small sized dispersion due to lower solute mobility at lower temperatures. 5 Refs.
