摘要：Functionally graded materials (FGMs) are a new kind of composite materials whose composition and microstructure varied continuously or stepwise from place to place in ways designed to provide it with the necessary properties at the specific regions of the components. Bulk FGMs with radial graded cores based on the SiC(p)/A1-2124 composite system fabricated by hot extrusion at 450°C have high surface hardness because of the SiC particulate reinforced Al-2124 matrix annulus combined with high interior toughness due to the introduction of an unreinforced Al-2 124 alloy central core. The tensile properties of bulk FGMs were elucidated in this study. The calculated and experimentally tensile results were compared. The results show that FGMs exhibit improved ductility but slightly lower 0.2% yield and tensile strength with respect to their conventional composite counterparts.
