J. Cent. South Univ. (2012) 19: 17-21 DOI: 10.1007/s11771-012-0966-9 Effect of heat treatment of Mn-Cu precursors on morphology of dealloyed nanoporous copper TAN Xiu-lan(谭秀兰)1, LI Kai(李恺)1, NIU Gao... a free corrosion method. The effects of heat treatment of Mn-Cu precursors on alloy phase, morphology and composition of the resultant nanoporous copper were investigated. It is revealed......
. The grain size of thermo-mechanically treated alloys is barely affected by cold working. The fracture strength and ductility increase significantly with the increase of misch metal content when tensile test is carried out below Mf temperature. Also, the fracture strength is larger in the case of post-quench ageing treatment than that in the case of direct quench ageing treatment. The fracture mode......
