Using the equilibrium phase diagram shown in Figure, answer the following questions for an alloy. $60$ wt$.\%Pb-40$ wt$.\%5n$:$(2+3+10+10)$ does the alloy become completely solld?

Draw and label the cooling curve of the alloy.

$($ii$.$ If you cool the alloy to $100C,$ what phases will be present in the alloy? If the alloy consists of two phases at that temperature, determ

iv$.$ Illustrate the microstructural development of the alion it completely

Draw the iron $-$ iron carblide phase diagram and label completely. $(10)$
