The Ag-Pb-Sn ternary system is an important material system for both electronic packaging and thermoelectric applications. However, there is no experimental phase equilibria information of the ternary system. Ag-Pb-Sn alloys are prepared and their phase equilibria at various temperatures were ...
In the latter case, concentrational and baric paths in the phase diagram pass near the tricritical Lifshitz point where the LP and TCP lines converge. The LP line position and the existence area of incommensurate phase are determined at T = OK on the T-x-y diagram of (PbySn1-y)2P2(...

Phase diagram investigation of the Cu–Sn system was carried out on twenty Cu-rich samples by thermal analysis (DTA), metallographic methods (EPMA/SEM-EDX) and crystallographic analysis (powder XRD, high temperature powder XRD). One main issue in this work was to investigate the high temperature...
