Problem

For the $Pb-Sn$ alloy system,

$($a$)$ What is the compositions and relative

amounts of the phases that constitute

the eutectic microstructure?

$($b$)$ For an alloy containing $30\%Sn,$

$($i$)$ What are the relative amounts of

$$ and $$ phases present at the

eutectic temperature?

$($ii$)$ What are the relative amounts of

the eutectic and the proeutectic $$

phase present at the same

temperature?
