Effects of Vacuum Hot Pressing Conditions on Mechanical Properties and Microstructures of $SiC_w$ /2124Al Metal Matrix Composites
Vacuum Hot Pressing 조건이 $SiC_w$ /2124AI 금속복합재료의 기계적 성질 및 미세구조에 미치는 영향
Abstract
The variation of the microstructures and the mechanical properties with varying vacuum hot pressing temperature and pressure was investigated in PyM processed 20 vol%) SiCw/ 2124Al composites. As increasing the vacuum hot pressing temperature, the aspect ratio of whiskers and density of composites increased due to the softening of 2124Al matrix with the increased amount of liquid phase. The tensile strength of composite increased with increasing vacuum hot pressing temperature up to
