摘要：

Fibre-matrix interfaces were investigated in alumina-short-fibre-reinforced aluminium alloys. The composites were produced by squeeze casting using pre-forms made of delta-alumina fibres (Saffil) or of alumosilicate fibres. Mostly the common piston alloy AlSi12CuMgNi was used as the matrix alloy, but some investigations were also performed on composites with a matrix of technically pure aluminium and the eutectic AlSi12 alloy. The piston alloy was used without any modification, with a strontium modification and with a lithium addition respectively. The composites were heat treated at 500-degrees-C for up to 60 days to study the thermal and chemical stabilities of the interface. The interfaces were investigated mainly by analytical transmission electron microscopy. The results are discussed with respect to wetting, adhesion and fibre-matrix reactions.
