Title: Iron-Carbon Phase Diagram

Answer the following questions:

Q: What is the weight% of carbon in the austenite phase of an iron-carbon alloy at 1300C and 2.5 global weight% of carbon? [...]
A: 1.25/1.25%
Q: What is the weight% of carbon in the liquid phase of an iron-carbon alloy at 1300C and 2.5 global weight% of carbon? [...]
A: 3/3%
Q: If instead I was at 500C with the same composition (2.5 gloabl weight % of carbon), what percentage of the material is ferrite (alpha phase)? (hint: we are not asking for the composition of carbon but the fraction of the solid and you can round to the nearest whole percentage) [...]
A: 62%/63%/64%
