依据Ａｌ基体极易被烧碱水溶液腐蚀，而ＴｉＣ和ＡｌＮ陶瓷粒子化学稳定性很高而不易被碱水溶液腐蚀的特点，采用１０％ＮａＯＨ腐蚀法对ＴｉＣ－ＡｌＮ／Ａｌ复合材料进行了两种增强体的体积分数的分别定量测定。实验证明这种方法对自生金属基复合材料增强体体积分数的测定简单、有效，从而对更精确的研究自生金属基复合材料微观组织与力学性能的关系提供了良好的数据基础。
Based on the fact that the Al matrix is easily corroded by the aqueous solution of caustic soda and the chemical stability of the TiC and AlN ceramic particles is so high that it is not easily corroded by aqueous alkali solution, two reinforcements of the TiC-AlN / Al composite material are subjected to 10% NaOH etching Of the volume fraction of the respective quantitative determination. Experiments show that this method is simple and effective for the determination of the volume fraction of self-forming metal matrix composites, which provides a good data basis for more accurate study of the relationship between the microstructure and mechanical properties of self-forming metal matrix composites.
