Abstract
ABSTRACTThis paper presents strong evidence for the influence of the density of oxide particles on the internal oxidation kinetics of silver based alloys. Measurements performed by Mbssbauer Spectroscopy, on 1 at% Sn in Ag alloys oxidized at temperatures between 523 and 823K, clearly indicate that the oxidation kinetics are described by a power law of the time with an exponent close to the unity for a high density of oxide particles (between 0.3 and 1.0×10−2 oxide particles per alloy atom). For low densities (<10−4 oxide particles per alloy atom), the exponent is close to 0.5). Previous kinetics measurements in AgIn alloys are shown to be in general agreement with this rule. These results can be interpreted on the basis of the existence of strain fields around the oxide particles, which produce a network of channels for easy oxygen migration when the density of oxide particles is high enough.
