摘要：

A mathematical model is developed for the effect of the oxide growth stress upon the high temperature deformation of metal. The growth stress is modeled as a volumetric strain calculated from a modified Pilling-Bedworth ratio. The model is three-dimensional and allows the metal and the oxide scale to undergo both elastic and creep deformation during oxidation. The problems of oxidizing a flat plate, a solid rod, and a curved plate are formulated and solved. Experimental results for these geometries in the Ni-NiO system at 1000 °C are well predicted, both with and without an external load. The creep properties and the stress distribution in the NiO scale are calculated. © 1991 The Minerals, Metals and Materials Society, and ASM International.
