Fabrication, Properties and Microstructures of High Strength and High Conductivity Copper-Silver Wires / Otrzymywanie Oraz Własności I Mikrostruktura Wysokowytrzymałych I Wysoko Przewodzących Drutów Ze Stopów Cu-Ag

Abstract: Research results of manufacturing composite filamentary nanostructure Cu-Ag alloys with silver addition from 5 to 15% wt. are presented in the paper. Manufacturing technology of these composites and variable solubility of silver in copper and copper in silver in the range of solid solutions. Suitable quantity and processing sequences of high deformation plastic working and heat treatment allows to obtain wires constituted from Cu and Ag fibres with nanometric transverse dimensions and in consequence provide to… Show more

“…The appearance of peak shoulders or significant skews to the right in CuAu/Cu (Figure S7d) and CuPd/Cu (Figure S8d) indicate the incorporation of Au/Pd into Cu domains and the formation of alloys. The observation of alloys on CuPd, CuAu, and CuPt but not on CuAg is due to their more favorable mixability between two metal atoms, which is supported by the phase diagram of Cu-based alloys. In addition, similar to CuPt/Cu, XPS analysis of all bimetals show the Cu 2 O-dominated surfaces and that M exists in its metallic chemical state.…”

“…Therefore, diffusion from Cu to Ag requires less energy than diffusion from Ag to Cu, while diffusion from Cu to Au requires greater activation energy than diffusion from Au to Cu. Based on the phase diagrams of Au-Cu [21] and Ag-Cu [22], AuCu3 may exist at 200 °C if an alloy is formed between Au and Cu, but Figure 4a,c show no evidence of the formation of the AuCu3 alloy. For Ag-Cu, mostly the α phase, which is the Cu phase, may exist at 200 °C with a minuscule amount of the α phase.…”

“…In addition, the bonding temperature of semiconductors varies depending on the product, but low temperatures below 250 °C are increasingly required. Cu bonding using a metal passivation layer can be applied to products either ultra-fine pitch Cu pad structures or larger Based on the phase diagrams of Au-Cu [21] and Ag-Cu [22], AuCu 3 may exist at 200 • C if an alloy is formed between Au and Cu, but Figure 4a,c show no evidence of the formation of the AuCu 3 alloy. For Ag-Cu, mostly the α phase, which is the Cu phase, may exist at 200 • C with a minuscule amount of the α phase.…”

“…Copper–silver systems show limited solubility in each other and form solid solutions. However, a temperature of about 779°C is required for the eutectic transformation to occur, as indicated in the Cu–Ag phase diagram [45] Therefore, it should be noted that in our current study, since the compact production was carried out at 500°C, solid solution formation is not in question, but it is considered as a mixture of copper and silver metal phases.
