摘要：

A nonsteady-state diffusional analysis has been applied to the oxidation of binary multiphase alloys. In addition to the solubility of the solute element in the continuous solid-solution phase, the volume fraction and the size of the second-phase particles have been found to be crucial for the exclusive formation of the solute oxide. By solving the diffusion equations, the oxidation behavior of a multiphase alloy has been quantitatively related to a microstructure parameter, P(L), which is a function of both the volume fraction and shape of the second phase. Moreover, the effectiveness of alloying for alloys with differently shaped second-phase particles on the oxidation of multiphase alloys has been discussed.
