Aluminum based Composite by Novelty Process: Repetitive Press Roll Bonding (RPRB)

Composite is a combination of two or more materials to improve the mechanical and physical properties. Strengthening and improvement of mechanical and physical properties on element of metal matrix and ceramic reinforced materials depend on diffusion in the micro-structure. Diffusion of liquefaction on materials usually requires coupling agent as a wetting agent. But in the high pressing will be able to generate diffusion on aluminum as the matrix material and Al2O3 nanofiber as reinforcement. Merging process for accumulated pressuring and rolling process by high pressure, expected to produce a uniform microstructure and ideal properties. This paper describes Aluminum based composite by Repetitive Press Roll Bonding (RPRB), which is a process of severe plastic deformation that combine accumulative press bonding with the rolling process. To ensure phenomenon of the recrystallization, finite element analysis was used to help study the effect of temperature on the microstructure changes that occur on Al/Al2O3 nanofiber based on composites.
