초록
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 660oC. Above sintering temperature of 640oC, 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.
