摘要
我公司为某用户生产的2A50铝合金棒材,用户认为有"夹杂"缺陷,我们对缺陷进行宏观组织和显微组织观察及分析,得知其缺陷并不是"夹杂",而是机加工零件上破坏金属表面的腐蚀斑。
The customer thinks that 2A50 aluminium alloy rod and bar supplied by our company has inclusion defect. The defect has been tested through observing and analyzing of macrostructure and microstructure. It follows that the defect is not＂inclusion defect＂, is the corrosion spot damaging the metal surface.
