Trans. Nonferrous Met. Soc. China 24(2014) s157-s161 Selective recovery of Sn from copper alloy dross and its heat-treatment for synthesis of SnO2 Jung-Il LEE1, Jong Bum PARK1, Tae Wan KIM1, Man-Sik... and separation of tin (Sn) from copper alloy dross by selective dissolution method was conducted. The tin in the copper alloy dross did not dissolve in an aqueous nitric acid solution which could allow......
Effect of Deformation and Heat Treatment on Morphology of Cr Phase and Mechanical Properties of Copper Alloy肖念新,张海龙摘 要:The effect of various cold deformation quantity and heat treatment on morphology of Cr phase and mechanical properties of copper alloy containing RE were studied. The results show that when reduction is to 70%, Cr phases are deformed......
id="ChDivSummary" name="ChDivSummary">Porous copper was prepared successfully by physical vacuum dealloying method using the Cu Zn alloy precursors(Cu30Zn70, Cu40Zn60 and Cu50Zn50 alloys). The micron porous copper showed a three-dimensional continuous porous structure with 1–5 μm pore size. With the increase of the Zn content in the CuZn alloy, the pore structure of the porous copper was more......
