复合材料金相试验方法研究

Investigation on microstructures of composites with metallographic tests

分别采用常规黑白金相、彩色金相、微差干涉衬度试验方法对长纤维增强、短纤维增强、颗粒增强金属基复合材料显微组织进行了研究 ,结果表明 :三种试验方法虽各有其自己的优缺点 。

The microstructures of metal matrix composite materials reinforced by long-fibres, short-fibres and particles respectively were investigated with black and white metallographs, color metallographs and elementary errors interference substrates, respectively. The results show that the elementary errors interference substrate way is superior to the other ways.
