Effect of solubility on strengthening of Ag–Cu ultrafine eutectic composites

Five decades of research on the development of eutectic as engineering materials

“…Among all Cu-based eutectics, the Cu-Ag eutectic is one of the most studied alloys. In general, this eutectic exhibits a well-defined lamellar microstructure [83][84][85][86]. The eutectic, with higher undercooling or growth rate, displays a feathery lamellar morphology that coexists with dendritic or colony structure with a two-phase irregular eutectic morphology.…”

Simulation of temperature field, flow field and solidification structure for Ag–28Cu–2Ge–0.4Co alloy

“…However, there are still few reports on related studies about the simulation of the temperature fields, flow fields and solidified structures for the precious metals. Ag-28Cu-2Ge-0.4Co alloy is one of the most widely used electronic solders due to its good fluidity, permeability and welding performance [13][14][15]. The solidification process of the casting is very complicated, and it is difficult to measure temperature and flow rate at multiple test points.…”

Microstructure refinement and hardening of Ag–20wt.%Cu alloy by rapid solidification

“…The mechanical properties of these alloys are significantly influenced by the presence of eutectic microstructures, which arise from the solidification process [1]. In particular, a refinement of the microstructure with a consequent increase of hardness can be obtained by rapid solidification techniques such as copper mould casting, [1,2] and glass fluxing technique [3][4][5]. However, few data are available for these alloys prepared by means of melt spinning and planar flow casting techniques [6,7], which might lead to a microstructure refinement of eutectics down to the nanoscale, giving a further improvement of mechanical properties [8].…”
