摘要
3003铝合金在300℃蠕变试验中发现两种类型的金属间析出物。析出物为a = 1.2556 nm具有简单立方结构的Al12(MnFeCu)3Si2析出物和a = 0.6506 nm, b = 0.7501 nm, c = 0.8800 nm具有正交结构的al6mn型析出物。高分辨率点阵成像表明，在多晶Al12(mnfeu)3Si2析出物中存在许多缺陷结构。
Two types of intermetallic precipitates were found in aluminum alloy 3003 creep tested at 300°C. These precipitates are an Al12(MnFeCu)3Si2 precipitate having a simple cubic structure with a = 1.2556 nm and an Al6Mn-type precipitate with an orthorhombic structure with a = 0.6506 nm, b = 0.7501 nm, and c = 0.8800 nm. High resolution lattice imaging indicated the presence of a number of defect structures in the polycrystalline Al12(MnFeCu)3Si2 precipitates.
