The purpose of this research was to develope a new whisker/aluminum alloy compounds. Silicon carbide (SIC) whisker/aluminum alloy (A6061) composites were prepaired by powder metallurgy (P/M). The mecanical properties and wear properties of the composites were investigated.1. The damage and dispersion of whisker in the composites were affected by the mixing method and the extrusion process. 2. The tensile strength of composites increased with adding sic whisker up to 5%. 3. The wear resistance of composites were improved three times of aluminum alloy by adding SiC whisker.

本研究旨在开发一种新型晶须/铝合金复合材料。采用粉末冶金法（P/M）制备了碳化硅（SiC）晶须/铝合金（A6061）复合材料。研究了复合材料的力学性能和磨损性能.晶须在复合材料中的分散和损伤受混炼方法和挤出工艺的影响。2.复合材料的拉伸强度随着晶须含量的增加而增加，当晶须含量达到5%时，复合材料的拉伸强度增加。3. SiC晶须的加入使复合材料的耐磨性提高了3倍.
