Özet

This study is conducted to study effect of sintering path on properties of Al matrix composites. For experimental study Al matrix is supported by two different ceramic powders including TiC and ZrO2 at different weight ratios 5 % and 10 %, respectively. To provide homogeneous distribution ingredients are ball milled for ten minutes at 100 rpm.  Then powder mixtures are compacted by a hand press under a 300-ton load.  After compaction Ф25 x 5 mm sized composite specimens are sintered by 4 different heating paths. SEM and XRD analyzes are conducted on powder mixtures. And properties of the composites are investigated by means of density, porosity, hardness, microhardness and optical microscopy. As a summary, the biggest hardness and experimental density values are observed at Specimen 2 which is sintered by a gradually heating route starting from 300 °C. And the Specimen 1 which is sintered by one step heating shows the biggest porosity and lowest hardness values.
