Abstract

A SiCp/Al composite was fabricated by the pressureless infiltration of an Al-Mg-Si alloy into the pre-oxidized SiC preform at 1000 °C for one hour. The composite fully infiltrated and a homogenous distribution of SiC particles was confirmed. MgAl₂O₄ was found as the interfacial reaction product, its formation deriving from the reactions: 2Mg+ ^SiO2=2MgO+Si and 2MgO+4Al+3^SiO2=2^MgAl2 ^O4+3Si. The factors influencing the spontaneous infiltration process were also discussed.
