Answer:
The volume percent of graphite is 91.906 per cent.
Explanation:
The volume percent of graphite () is determined by the following expression:
Where:
- Volume occupied by the graphite phase, measured in cubic centimeters.
- Volume occupied by the ferrite phase, measured in cubic centimeters.
The volume of each phase can be calculated in terms of its density and mass. That is:
Where:
,
- Masses of the graphite and ferrite phases, measured in grams.
,
- Densities of the graphite and ferrite phases, measured in grams per cubic centimeter.
Let substitute each volume in the definition of the volume percent of graphite:
Let suppose that 100 grams of cast iron are available, masses of each phase are now determined:
If ,
,
and
, the volume percent of graphite is:
The volume percent of graphite is 91.906 per cent.
