Whiskers of Al2O3 as reinforcement of a powder metallurgical 6061 aluminium matrix composite

An Al–Mg–Si alloy matrixcomposite reinforced with 10 vol.% of alumina whiskers (Al2O3w) has been processed by powder metallurgy and investigated. The Al2O3w were produced as single crystal c-axis alpha-alumina fibres at pre-pilot scale via vapour–liquid–solid (VLS) deposition in a cold-wall air-tigh...
