Experimental Investigation of SiCp_A356 Composites

Article Preview

Abstract:

The mechanical behaviours of SiCp_A356 composite at room and elevated temperature were investigated. The yield strength, the tension limit and Young’s modulus drop obviously with the rising temperature. The hardening cycle occurs during 20°C~150°C, but weakens with rising temperature. The softening cycle appears between 200°C~300°C, but increases with rising temperature. The relaxation performance is similar to that of a normal metal material. The creep constitutive model was presented and finally the micro fracture mechanics was analyzed.
