Abstract

The high temperature creep and cyclic creep behaviours of SiC_w/6061Al and SiC_p/2024Al composites were studied at 298°C. It was found that SiC_w/6061Al composite showed better creep resistance but lower creep threshold stress as compared to SiC_p/2024Al composite. Both composites showed cyclic creep retardation (CCR) in the tested stress region, while the CCR for SiC_p/2024Al composite was more pronounced. For the SiC_w/6061Al composite, the minimum cyclic creep rate decreased first and then increased with increasing the unloading amount, while for the SiC_p/2024Al, the minimum cyclic creep rate decreased monotonically with increasing unloading amount.
