“…It suggests that the formation of Cu 3 Sn is induced by the reaction between Cu 6 Sn 5 and Cu element, following as Cu 6 Sn 5 +Cu→Cu 3 Sn. The stress provides adequate deformation in the inner structure of Cu 6 Sn 5 , which supplies a diffuse alleyway of atoms for Cu element [4]. As the milling time reaches 40 h, only Ag 4 Sn, Cu 6 Sn 5 and Cu 3 Sn are detected in the sample, which indicates that the alloying process of (Ag-Cu 28 )-30Sn has finished.…”

“…Therefore, developing ageing-resistant alloy welding materials with a melting temperature of 400-600°C has a momentous significance for increasing the service life and product performance of TWT. So far, the reported alloy systems mainly include Au-Ge, Au-Ag-Si, Ag-Cu-Sn, Ag-Cu-Sn-In, and others [1][2][3][4], which still show poor melting properties compared to organic welding materials.…”

To obtain novel intermediate temperature alloy solders with a melting temperature of 400-600°C, nominal (Ag-Cu 28 )-30Sn alloys without or with a trace addition (0.5 or 1.0 wt.%) of rare earth (RE) element La were prepared by mechanical alloying. The aim of this research is to investigate the effects of the addition of La on the microstructures, alloying process and melting properties of (Ag-Cu 28 )-30Sn alloys. The results show that the addition of La produces no new phase. A trace amount of La addition can effectively refine the grain size, but the excessive addition of 1.0 wt.% La inhibits the alloying process. The influence of La on the melting temperatures of solder alloys is negligible. However, the trace addition of 0.5 wt.% La can distinctly reduce the fusion zone and improve the melting property of (Ag-Cu 28 )-30Sn alloys.

“…So the intermediate temperature alloy solders with melting temperature of 400~600°C have recently become of great interest owing to their potential use as novel vacuum welding materials. The reported suitable alloy systems as intermediate temperature alloy solders mainly include Au-Ge, Au-Ag-Si, Ag-Cu-Sn and Ag-Cu-Sn-In, etc [1][2][3][4] so far.…”

To obtain novel intermediate temperature alloy solders with melting temperature of 400~600°C, (Ag-Cu28)-25Sn alloy ribbons were prepared by high frequency induction melting and melt spinning at different quenching linear speed. The effect of the development of solidification structure on melting properties and microhardness of the ribbons were investigated. The XRD results show that the as-prepared alloy ribbons have the same phase composition as the master alloy, which consists of Ag4Sn and Cu3Sn. With the quenching linear speed increasing, the solidification structures are refined and change from dendritic crystals to uniform granular crystals. As the quenching linear speed increases up to 32.25m/s, the grain size of the alloy ribbon has a distribution ranging from submicron to about 2μm. The DSC results indicate that the melting properties of alloy ribbons strongly depend on the solidification structure, and the melting temperature of alloy ribbons decreases with the quenching linear speed increasing. The lowest liquidus points of the alloy ribbon prepared at linear speed of 32.25m/s are located at 473.6°C and 524.7°C, respectively. The refined solidification structure notably increases the microhardness of the alloy ribbons, and the largest hardness value of 396HV is obtained for the alloy ribbon prepared at linear speed of 32.25m/s, which increases 27.0% compared with the master alloy.
