, and aluminum. The possible formation mechanism of amorphous [Al-Si-O] layer was proposed: During discharge periods, Al2O3 phase of the passive film and SiO32-near the substrate surface are sintered into xSiO2(1-x)Al2O3 and then transformed into amorphous [Al-Si-O] phase. 关键词:plasma electrolytic deposition; amorphous layer; aluminum alloy; [全文内容正在添加中] ......

Effect of evolution of polycrystalline textures onr-value of LF2 aluminum alloy ZHAO Yi-xi(赵亦希), LIN Zhong-qin(林忠钦), LI Shu-hui(李淑慧), YU Zhong-qi(于忠奇) School of Mechanical Engineering, Shanghai... of aluminum alloy sheet was investigated. For this purpose, the textures under different elongation of LF2 aluminum alloy were measured and analyzed. The result indicates that the initial texture of LF2......
a new Al–Cu–Mg alloy which was known as 2026 aluminum alloy in 2001 [5]. At the basis of the predecessor 2024 aluminum alloy, 2026 aluminum alloy containing less natural impurities (Fe and Si... in the Al–Cu–Mg alloys, and difficult to be completely eliminated by homogenization treatment [6, 7]. Therefore, the optimum homogenization process of 2026 aluminum alloy is at 490 °C for 24 h. Figure 5......
