Compute the volume percent of graphite, $V_{Gr}$, in a 3.5 wt% C cast iron, assuming that all the carbon exists as the graphite phase. Assume densities of 7.9 and 2.3 g/cm³ for ferrite and graphite, respectively.
Part 1
What is the weight fraction $W_{\alpha}$?
$W_{\alpha}$ - i
Part 2
What is the weight fraction of graphite?
$W_{Gr}$ - i
Part 3
What is the volume fraction of graphite?
$V_{Gr}$ - i
