Abstract
Ceramic powder dispersed or whisker-reinforced Al composite was produced by hot pressing at 973K and exposure to high temperature of 1523K. The mechanical properties and micro structures of each composite were examined by a three-point bending test, hardness tester, scanning electron microscopy, X-ray diffraction patterns and XMA analysis.
The present method was found more effective for obtaining the whisker reinforced Al composite than a powder dispersed Al composite. The powder dispersed Al composite following heattreatment at high temperature maintained its mechanical strength owing to fewer pores and cracks.
