Trans. Nonferrous Met. Soc. China 22(2012) s820-s824 Microstructure of fast tool servo machining on copper alloy Hong LU1, Soo-chang CHOI2, Sang-min LEE1, Deug-woo LEE3 1. Department of Nano Fusion... performance of a piezoelectric-assisted FTS on copper alloy was evaluated. The results indicate that the quality of the microstructure depends mainly on two important factors: the cutting speed......

J. Cent. South Univ. (2017) 24: 335-340 DOI: 10.1007/s11171-017-3435-2 Dissolution kinetics of copper from multi-metal copper alloy roasted in oxygen LU Wei-hong(卢伟红), YIN Zhou-lan(尹周澜), DING Zhi... Abstract: A kinetic study on the sulfuric acid leaching of multi-metal oxide, which is the product of multi-metal copper alloy with iron trioxide roasted in oxygen, was carried out. The effects of leaching......
J. Cent. South Univ. (2018) 25: 754-763 DOI: https://doi.org/10.1007/s11771-018-3780-1 Effect of additives on anode passivation in direct electrolysis process of copper–nickel based alloy scraps LI... passivation time. Over this range, glue and thiourea played an adverse effect. The increase of chloride ions concentration led to the increase in passivation time. Key words: copper–nickel based alloy......
concentrations of (T=298 K) Fig.3 and Fig.4 show the lgC-pH curves for each copper species and copper ammonia species in solution system (T=298 K), respectively. From Fig.3, it can be found that free copper ions are dominant in the solution when pH is less than 5.0. When 5.0＜pH＜8.0, the concentration of free copper ions decreases with the concentration of ammonia increasing and most of the copper......

Hot deformation behavior of KFC copper alloy during compression at elevated temperatures ZHANG Hui(张 辉)1, 2, ZHANG Hong-gang(张红钢)3, PENG Da-shu(彭大暑)2 1. College of Materials Science...; Abstract: The hot deformation behavior of a KFC copper alloy......
. However, the seawater of Xiamen inhibits the pitting corrosion of copper alloys. No pitting corrosion is observed on copper alloy plates tested there. The copper alloys suffer from more serious pitting corrosion in the tide zone than that in the immersion zone at Qingdao after long time exposure. Key words: copper alloy; seawater exposure; pitting corrosion CLC number: TG146 Document code: A 1......
