Title: Effects of Rolling on the Microstructure and Properties of 7075/SiCp Composite
Abstract: The microstructure and mechanical properties of the extruded and rolled plates of spray co-deposited 7075/SiCp composites were tested and analyzed. After the composite's being extruded and rolled, the SiC particles distributed along the direction of the metal plastic flow. The size of the particles reduced markedly in the rolling process. The peak ageing strength and elongation value of the rolled composite were higher than those of the extruded composite. The fractographies show that the tensile fracture is resulted from Al/SiC interfacial debonding and SiC particles' fracture for the extruded composite, but from Al/SiC interfacial debonding and matrix failure for the rolled composite.
