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.

The main aim of this work was to study the effect of time and method of Al, SiC powders mixing on the microstructure and mechanical properties of composites. Moreover, the influence of applicating direct extrusion with a reversibly rotating die on the homogeneity of the composites was examined. Microstructure observations with the use of an optical microscope and scanning electron microscope were applied. A quantitative analysis of composite microstructure was conducted. The density (helium pycnometer method), Vickers hardness and the Young’s Modulus of the composites were also determined. The results show that the homogeneity of Al/SiC composites rises with an increase of mixing time. However, better results were obtained by application of high energy ball milling process.
