Aluminum Alloy, Discontinuously Reinforced Hot Isostatically Pressed Shapes 6061B/SiC/40p (3μm) (T1P)
|Publication Date:||1 July 2017|
This specification 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).
HIP'ed shapes have been used typically for structural applications requiring high static strength, fatigue strength and high elastic modulus, but usage is not limited to such applications. HIP'ed shapes may also be used as input to forging, rolling and extrusion processes. Subsequent heat treatment to the T6P/T62P temper is required to increase strength to levels required for service (see 3.4 and 3.4.1).
