Summary:

As transport aircraft technology has progressed from subsonic to supersonic and now toward hypersonic applications, the demand for low-cost, lightweight, and high-strength materials for complex structural components has prompted the development of particulate-reinforced metal matrix composites (MMCs). Despite extensive room temperature evaluations of these MMCs, the toughness, creep, and welding properties of such materials when placed under high-temperature conditions have received little attention. In this paper, the effects of temperature on the tensile properties, fracture toughness, and related creep behaviors of a silicon carbide particulate reinforced 2124-T6 aluminum alloy matrix composite (SiCp/Al 2124-T6 MMC) are evaluated. To carry out this testing, variations in this material's mechanical properties, residual stresses and microstructure near welded joints and crack tips originating from machined notches were investigated
