5、inforced Hot Isostatically Pressed Shapes2124A/SiC/25p (3Pm) (T1P)RATIONALEAMS4355 is a new specification for aluminum alloy hot isostatically pressed shapes produced from 2124A discontinuously reinforced with silicon carbide particulates.1. SCOPE1.1 Form This specification covers discontinuously re

6、inforced aluminum alloy (DRA) metal matrix composites (MMC) made by mechanical alloying of the 2124A powder and SiC particulate, which is then consolidated by Hot Isostatic Pressing (HIP) into shapes less than 62 in2(0.04 m2) cross-section (see 8.11). 1.2 Application HIPed shapes have been used typi

7、cally for structural applications requiring high static strength, fatigue strength and high elastic modulus, but usage is not limited to such applications. HIPed shapes may also be used as input to forging and extrusion processes.2. APPLICABLE DOCUMENTSA change bar (l) located in the left margin is
