本文介绍了碳化硅颗粒（SiC - p）增强铝金属基复合材料的力学性能和可加工性的实验研究结果。研究了5%、10%和15%（重量比）的SiC - p增强比例对力学性能的影响。还研究了加工参数，例如切削速度、进给量和切削深度对刀具磨损和表面粗糙度的影响。观察到增强元素添加量的增加产生了更好的力学性能，如冲击韧性和硬度，但抗拉强度呈现不同的趋势；在SiC - p增强量达到10%（重量比）时增加，然后在SiC - p增强量为15%（重量比）时下降。对所选材料的可加工性进行了研究，发现较高的SiC - p增强量会导致较高的刀具磨损；表面粗糙度通常受进给量和切削速度的影响。（C）2007爱思唯尔有限公司。版权所有。
The paper presents the results of experimental investigation on mechanical and machinability properties of silicon carbide particle (SiC-p) reinforced aluminium metal matrix composite. The influence of reinforced ratios of 5, 10 and 15 wt.% of SiC-p on mechanical properties was examined. The effect of machining parameters, e.g. cutting speed, feed rate and depth of cut on tool wear and surface roughness was studied. It was observed that increase of reinforcement element addition produced better mechanical properties such as impact toughness and hardness, but tensile strength showed different trend; increased upto 10 wt.% of SiC-p reinforced and then decreased when 15 wt.% of SiC-p reinforcement addition. Machinability properties of the selected material were studied and higher SiC-p reinforcement produced a higher tool wear; surface roughness was generally affected by feed rate and cutting speed.
