The Sn-Cu-Ni has become increasingly significant as it is used in several solder alloys and more generally both Cu and Ni are common substrates that interact with Sn-based solders in microelectronic applications. However, there is currently an insufficient understanding of the phase equilibria and the associated phase diagrams of many Sn alloys. mass fraction of each phase is 0.5, estimate: (a) The temperature of the alloy (b) The compositions of the two phases Solution (a) We are given that the mass fractions of α and liquid phases are both 0.5 for a 30 wt% Sn-70 wt% Pb alloy and asked to estimate the temperature of the alloy.

Eutectic 1. We have examined isomorphous phase diagrams, and used the example of the Cu-Ni phase diagram. In this module we will examine eutectic phase diagrams. A eutectic system has two components, and they have limited solubility. Upon cooling, the liquid will transform into two mixed solid phases. We will use the Pb-Sn phase diagram as an ...

This reaction is relatively uncommon, but has been seen to occur in Ni-Zn, Fe-Cb, Cu-Sb, Cu-Si, Cu-Sn, Ni-Mo, Ni-Si, Fe-Au systems. Peritectoid reaction is related to the peritectic reaction as does a eutectoid reaction to a eutectic. It occurs in the solid state (only solids are involved in it) due to thermal instability of a specific phase.
