on micro- structure were done in the last decade, no systematical study is focused on the microstructure of the cast ingot and aged alloys. ZHANG et al[10] studied the alloy phases and the microstructure in MB15 alloy (equal to ZK60 alloy), however they failed to report the morphologies of the alloy phases and their evolution during heat treatment. GU et al[11] studied the age hardening precipitation......
of Mechanics, Chinese Academy of Sciences, Beijing 100080, China) Abstract: Amorphous [Al-Si-O] coatings were deposited on aluminum alloy by plasma electrolytic oxidation(PEO). The process parameters... deposited on aluminum alloy. If sodium silicate(below 20g/L) is added in the electrolyte, the growth rate of the coatings is increased and the coatings consist of Al2O3 and Al-Si-O phase with complex......
of the structural aircraft parts. 2 EXPERIMENTAL The Al alloy assessed in this investigation was AA 7010-T7651 with a chemical composition of Zn 6.30, Mg 2.34, Cu 1.75, Zr 0.12, Fe 0.05, Si 0.04, Ti..., Mn or Si in solid solution in Al alloys would result in an increase in resistivity of 0.094, 0.344, 0.54, 1.74, 2.56, 2.88, 2.94 or 1.02μΩ·cm, respectively. The measured concentrations of Zn, Cu, Mg......
