铍铝合金显微组织的评定方法

Evaluation Methods of Microstructure of Be-Al Alloy

摘要: 对粉末冶金工艺制备的铍铝合金显微组织的评定方法进行了探讨.提出对该合金显微组织评定的4个定量参数：铍聚集区的最大尺寸、铝相区的最大尺寸、铍相和铝相的面积分布、铍相和铝相的综合颗粒大小.建议在金相检验中对这四方面的特征进行测量,以提高对材料组织的监测能力.

Abstract: The microstructure measurement methods of Be-Al alloy made by powder metallurgy were discussed.The quantitative parameters were presented including the biggest size of Be zone and Al zone, the area distribution and integrated particle size of Be and Al phase.It was suggested that these parameters should be measured in metallographic examination to improve the monitoring capacity of microstructure.
