铝硅合金铸件中裂纹缺陷的分析OA北大核心CSTPCD
Analysis of Crack Defects in AlSi Alloy Castings
从铝合金铸件中裂纹缺陷部位切取试样,利用扫描电子显微镜和能谱仪观察了试样的表面形貌与特征,分析了裂纹缺陷的形成原因.结果表明,裂纹缺陷主要是由于铸件中存在氧化夹杂以及脱落的脱模剂卷入金属液所造成的,两种裂纹特征有所差异.
The surface topography and chemical composition of the crack defects in the aluminum alloy castings were investigated by scanning electron microscope and energy spectrometer.The cause of the cracks were analyzed and discussed.The results show that the cracks are mainly resulted from the existence of release agents and oxide inclusions,and they are characterized with different length and depth.
