In the present work, 6061 Al-B4C sintered composites containing different B4C contents were fabricated and their characteristic were investigated as a function of sintering temperature. For this, composite powders and their compacts with B4C various contents from 0 to 40 wt.% were fabricated using a planetary ball milling equipment and cold isostatic pressing, respectively, and then they were sintered in the temperature ranges of 580 to 660o C. Above sin- tering temperature of 640o C, real density was decreased due to the occurrence of sweat phenomena. In addition, it was realized that sinterability of 6061Al-B4C composite material was lowered with increasing B4C content, resulting in the decrease in its real density and at the same time in the increment of porosity.
