A continuum mechanics model which incorporated the effect of dynamic recovery was developed to explain the deformation behavior of metallic materials with ellipsoidal second-phase particles at elevated temperatures. A theoretical discussion based o this model was made on the effect of several factors including shape, particle size, orientation and elastic modulus of second phase on the high-temperature deformation of the materials. It was assumed in this study that the dynamic recovery process was controlled by volume diffusion or grain-boundary diffusion of atoms. The result of theoretical calculation was then compared with that experimentally obtained by the present authors or other investigators for several kinds of metallic materials with ellipsoidal second-phase particles. Good agreement was found between the result of calculation and that of the experiment i those materials. The dynamic recovery model used in this study is applicable to the prediction of high-temperature work-hardening behavior, the design of high-temperature strength, and the understanding of the rate-controlling mechanism of recovery process in metallic materials with non-deforming second-phase particles.
