A model to attain a homogeneous particle distribution in bi-modal and tri-modal metal matrix composites produced by accumulative roll bonding is presented. Three cubic models, including simple, face-centered and body-centered cubic models, are considered for uniform distribution of particles in the matrix. Results show that the critical reduction to get a uniform distribution of particles rises with increasing volume fraction, decreasing particle size and raising initial layer thickness. The validity of the model is verified by accumulative roll bonded-metal matrix composites reported in literatures. Good agreement is observed between the model and the experimental data.
