Surface and transport properties of liquid Ag–Sn alloys and a case study of Ag–Sn eutectic solder

Machine learning search for stable binary Sn alloys with Na, Ca, Cu, Pd, and Ag

“…Structural solutions proposed since the compound's discovery in 1926 [154] include a disordered hcp phase [155], an orthorhombic displacive homeotype β-TiCu (Cmcm) [156], and the D0 a -Cu 3 Ti prototype (P mmn) [157]. The latest studies [48,50,[158][159][160] point to a general consensus that the equilibrium ϵ phase has the ordered Cu 3 Ti-type structure (oP8). Study of Ag-Sn compounds is of significant importance in the ongoing development of Pb-free solders for highperformance electronic devices [48,50,[161][162][163].…”

“…[45][46][47] Tin alloys have been extensively investigated as non-toxic alternatives to Pb-free solders and durable joint materials in electronics interconnects. 28,29,[48][49][50][51][52][53] The efforts have focused on finding tin intermetallics that can balance high mechanical stability, high thermal conductivity, resistance to Sn-whisker formation, cost effectiveness, and other factors important for next-generation integrated circuits. 48,50 A number of tin-based materials have been studied for their non-trivial topological behavior.…”
