對粉末冶金工藝制備的鈹鋁合金顯微組織的評定方法進(jìn)行了探討.提出對該合金顯微組織評定的4個(gè)定量參數(shù)：鈹聚集區(qū)的最大尺寸、鋁相區(qū)的最大尺寸、鈹相和鋁相的面積分布、鈹相和鋁相的綜合顆粒大小.建議在金相檢驗(yàn)中對這四方面的特征進(jìn)行測量,以提高對材料組織的監(jiān)測能力.
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.
