metal Calculating percentages of microstructures in

At 6.67% you have a crossover from a mix of $\ce{F3C}$ (cementite) and ledeburite to 100% cementite. There is no pearlite at this line. Since the goal was to determine the proportion of pearlite at 0.4%, we need a limit of 100% pearlite on one side (happens at 0.76%) and 0% pearlite on the other (0% C). $\endgroup$ Ben Norris Sep 23 '19 at

The weight percentage scale on the X-axis of the iron carbon phase diagram goes from 0% up to 6.67% Carbon. Up to a maximum carbon content of 0.008% weight of Carbon, the metal is simply called iron or pure iron. It exists in the α-ferrite form at room temperature. From 0.008% up to 2.14% carbon content, the iron carbon alloy is called steel.
