The properties of material is a function of the microstructure which depend on the overall composition and variable such as pressure and temperature. Hence to determine ... Tin / Silver (Sn / Ag ) Alloy Solders - Properties and ... Tin/Silver solders are used for high temperature, high reliability interconnect applications. Solder joints using Tin/Silver alloys maintain better high temperature strength then tin/lead solders. Key Properties The Tin 96.5/Silver 3.5 eutectic has a melting point of 221°C. The Tin 95/Silver 5 alloy has slightly higher melting point. Applications Example Phase Diagrams Figure 36-3: Phase diagram for Gold-Tin has seven distinct phases, three peritectics, two eutectics, and one eutectoid reactions. Figure: Phase diagram for Gold-Nickel showing complete solid solubility above about 800 C and below about 950 C.

PERITECTICS - A Practical Guide to Phase Diagrams On this diagram, the peritectic is at about 38 at% platinum and 1188°C. At this point, the pure silver phase, upon heating, will decompose into a liquid mixed with the pure platinum phase. The third feature we will discuss on this page is a peritectoid point. Standards & Properties: Metallurgy of Copper-Base Alloys If the tin content is increased to 11% or more, some of the alpha phase will transform as the metal cools below 400°C. A new phase appears, interspersed throughout the normal fcc alpha crystals. This phase, called delta, can be preserved in the material with fairly rapid cooling ( Figure 5 ). Figure 5. Tin-silver-copper eutectic temperature and composition ... A careful investigation of the Sn-Ag-Cu phase diagram near the ternary eutectic composition was undertaken using annealed alloys and differential scanning calorimetry to settle some uncertainties in the eutectic composition. The eutectic composition was found to be 3.5 wt pct Ag, 0.9 wt pct Cu, and the balance Sn. Solid-liquid Phase Diagrams: Tin and Lead The phase diagram Constructing the phase diagram You start from data obtained from the cooling curves. You draw a graph of the temperature at which freezing firststarts against the proportion of tin and lead in the mixture.
