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......
Effect of carbon on tribological property of plasma carburized TiAl based alloy LIU Xiao-ping(刘小萍)1,2, TIAN Wen-huai(田文怀)1, GUO Chao-li(郭朝丽)2, HE Zhi-yong(贺志勇)2, XU Zhong(徐 重)2 1... and the carburized depth is slightly thicker than that of alloy carburized at CH4?Ar of 6?5. The result of the ball-on-disk test against hardening-steel counter bodies shows that the wear resistance of the TiAl based......

, China) Abstract:A notch sensitivity factor was derived in order to evaluate the stress concentration sensitivity of Al-Li based alloys. The factor values for the Al-Li alloy sheets containing various... in the high ductility alloy 1420 can significantly increase the stress concentration sensitivity. As compared with conventional aluminum alloys, the Al-Li based alloys generally show high stress......
