abstract = "The effect of working temperature on microstructure and mechanical properties of ultrafine grained monolithic Al and Al-5vol.\%SiCp composite processed by accumulative roll bonding (ARB) was studied. The ARB was performed up to eight cycles (an equivalent strain of ∼6.4) without lubricant. The working temperature was varied from ambient temperature to 200° C. The samples processed at temperatures below 100°C exhibited an ultrafine grained structure over almost all regions. However, the samples processed at 200°C showed an inhomogeneous structure in which a few coarse grains due to an occurrence of conventional recrystallization is partially seen. The tensile strength of both the monolithic Al and the composite decreased with increasing the ARB working temperature. The variation of microstructure and mechanical properties of the composite with the working temperature was compared to that of the monolithic aluminum.",
