Use the iron-carbon phase diagram below to answer the following
questions. For phase mass fractions and composition, it
is expected that you will use a straight-edge and ruler (or
electronic equivalent). Note that there is a similar
diagram in Chapter 10 of the Callister text if you would like to
use it for reference. For the solid phase names, please
use the Greek letter notation (alpha, gamma, delta, etc.) or the
corresponding English nomenclature (ferrite, austenite, etc.)
