ASSIGNMENT LECTURE NOTE 3 
1. Explain what equilibrium phaso diagram is about? Explain with the ad of diagram. tho development of microstructure in bin, isomorphous system. 2. (a) Explain with the aid of diagram. the microstructure of eutectic Cu-Ag (b) An alloy of 40 wt, Ag-60 Cu alloy at 600.0 is depicted in Figure 01. Calculate the relative amount of each phase present in terms of. (i) mass fraction and. (ii) volume fraction (At 600.0 take the densities of Cu and Ag respectively to be 8 51 and 10.12 g,cm') 3. A copper-saver alloy is heated to 900.0 (Figure 01) and is found to consist of o and liquid phases If the rnass fraction of the liquid Phase 1.88. determine (a) the composition of both phases. in both weight percent and atom percent. and (b) the composition of the alloy. in both weight percent and atom percent.
