SAE AMS4368

SAE AMS4368 covers discontinuously reinforced aluminum alloy (DRA) metal matrix composites (MMC) made by mechanical alloying of 6061B aluminum powder and SiC particulate, which is then consolidated by Hot Isostatic Pressing (HIP) into shapes between 12 to 100 in2 (0.008 to 0.065 m2) cross-section inclusive. Tensile property response to heat treatment has been demonstrated on samples of 1 in2 (645 mm2) maximum cross section (see 8.9).
