Evaluation of Mechanical Properties and Structure of 1100-Al Reinforced with Zro2 Nano-Particles via Accumulatively Roll-Bonded

摘要

In this study, aluminium metal composites reinforced with Zirconium dioxide (ZrO2) nano-particles in different of volume percentage are manufactured through accumulative roll bonding. The results indicate that with the application of 10 ARB cycles and the composite microstructure shows excellent ZrO2 particle distribution in the Al matrices. The X-ray diffraction results also showed that nanostructured Al/ZrO2 Nanocomposite with the average crystallite size of 48.6 nm was successfully achieved by employing 10 cycles of ARB process. According to the results of this study, the tensile, hardness, and elongation properties of the Al/ZrO2 composite are determined for 0.50, 0.75 and 1 vol.% ZrO2.
