dc.description.abstractA dislocation assisted self-consistent model based on Tandon and Weng approach and Bergstrom dynamic recovery model for particulate-reinforced composites has been extended to consider the matrix evolution during high-temperature deformation on flow stress. The impact of main influential processing parameters such as temperature, strain, and strain rate in addition to reinforcement characteristics, including particle size, and volume fraction, were successfully taken into account in the constitutive model. Moreover, the effect of particle fracture, diffusion relaxation around particles, dynamic recrystallization, and dynamic recovery of the matrix during deformation were precipitated as the softening factors in the presented model. It was found that the occurrence of particle stimulating nucleation mechanism can destroy the load transfer mechanism, which results in flow curve softening for a limited range of deformation conditions. It was shown that deformation mechanisms in single-phase alloy and metal matrix composite are the same, which are viscous glide and dislocation climb.
