Novel Method

Abstract The aluminum metal-matrix composites reinforced with the micro- and nanoparticles of TiO2 were manufactured in the form of sheets through the accumulative roll bonding (ARB) process which has been lately considered as a novel method under an intense plastic deformation so as to produce particulate-reinforced metal-matrix composites. Themicrostructural examinations via optic microscopy and scanning electron microscopy (SEM) depict that the distribution of TiO2 particles in the aluminum matrix is almost uniform and also the dispersion of the microparticles of TiO2 is more homogeneous than that of the nanoparticles one. Furthermore, the tensile tests demonstrate the noteworthy enhancements in the tensile strengths of the composites, compared to the Al 1100 as the virgin metal, however, by attenuating the size of the particles, i.e. from micron to nano, the composite tensile strengths are augmented. The fractographic analysis of the fracture surfaces revealed that the fracture mode in the ARB-processed Al/TiO2 composite is the shear ductile rupture type.

Aluminium metal matrix composites reinforced with WC ceramic particles were manufactured through warm accumulative roll bonding (ARB) in this study. The microstructures of the composites exhibited excellent particles distribution in the matrices. Compared with the mechanical properties of ARB monolithic pure Al, the Al/WC composites exhibited higher tensile strength. The shear lag theory modified was used in considering the yield strength of the composites. The results indicated that the effects of WC particles in Al/WC composite lead to the thermal expansion dislocation strengthening, small subgrain strengthening, Orowan strengthening and geometrically necessary dispersion strengthening.
