Metals like silver and gold have a difference of 0.2%; nickel and copper of 2.7%, and show complete solid solubility. But zinc and copper have 4.2% difference with maximum solubility of 38.4 wt.% Zn. (other factors are less favourable); Cadmium in copper with 16.5% size difference shows a solid solubility of 1.7 wt.%. 10.4 Given here are the solidus and liquidus temperatures for the copper–gold system.

Copper-gold phase diagram. copper oxide is painted on the article and then gold balls are attached. The article is then placed in a reducing flame which causes the oxide to reduce to copper and then react and form a eutectic with the gold which disappears by diffusion. Several objects that are thought to have been bonded using this process peritectics, and congruent phase transformations for the tin-gold system (Figure 9.36). There are two eutectics on this phase diagram. One exists at 10 wt% Au-90 wt% Sn and 217°C. The reaction upon cooling is L → α + β The other eutectic exists at 80 wt% Au-20 wt% Sn and 280°C. This reaction upon cooling is L → δ + ζ Use the following silver-copper phase diagram for Problems 5-9. 5. What are the solubility limits of Ag in (Cu) and Cu in (Ag)? Recall that (Cu) and (Ag) are the same as α and β, respectively. The solubility limit of Ag in (Cu) is 7.9 wt. % Ag. The solubility limit of Cu in (Ag) is 8.8 wt.% Cu. Note that these Phase Diagrams • Indicate phases as function of T, Co, and P. • For this course:-binary systems: just 2 components.-independent variables: T and Co (P = 1 atm is almost always used). • Phase Diagram for Cu-Ni system Adapted from Fig. 9.3(a), Callister 7e.

The Au-Al phase diagram (Figure 14) contains a number of intermetallic compounds formed at compositions situated close to the gold-rich end of the diagram. AuAl2 has a gold content close to that of an 18 carat alloy (75 per cent gold), which makes it possible to produce a hallmarkable 18 carat purple alloy.
