On the achievement of uniform particle distribution in metal matrix composites fabricated by accumulative roll bonding

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.

► A model is developed to achieve a uniform reinforcement distribution during ARB.
► Critical reduction rises with raising volume fraction and layer thickness.
► The smaller the mean particle size, the higher the critical reduction.
► Good agreement is observed between the model and the experimental data.
► Among all three cubic models, the simple cubic model is more applicable.
