Abstract

Attempts have been made to describe the influence of sintering temperature on the microstructure and properties of Al - SiC composites. Mixtures of 100%Al and Al - 5% SiC, Al - 10% SiC were produced by tumbling for 30 minutes in the Turbula T2F mixer. The powders were subsequently cold pressed at pressure 300MPa in a rigid die on a single action press. The green compacts were sintered in nitrogen at 580°C and 620°C for one hour. The main objective of this work was to determine influence of chemical composition and the manufacturing parameters on microstructure and properties of Al - SiC composites produced by powder metallurgy technology.
