Paper Abstract

Aluminum alloys containing ceramic particulate reinforcement produce a lightweight metal matrix composite (MMC) with enhanced mechanical and physical properties including higher modulus and vibration loss. This paper will discuss Al-SiC MMC’s made from mechanical alloyed (MA) powder. Consolidated MA powder can produce isotropic MMC’s with micron to submicron mean particulate reinforcement size, increasing mechanical properties in comparison to MMC’s with larger particle size plus results in a material that can be machined or metal worked using conventional methods. The microstructure, properties and emissivity of MMC’s MA’d with base aluminum alloys 6061B and 2124A will be presented including approved SAE-AMS compositions.
