Ferrite vs pearlite
WebPearlite: Pearlite is the name given to a mixture of about 87.5 percent ferrite and 12.5 percent cementite. It consists of alternate layers of ferrite and cementite in steel. Under high magnification the ferrite and cementite can be seen to be arranged in alternate … Diffusional transformations like austenite transforming to a cementite and ferrite … This line tells us the steel having carbon up to 0.8% up to 0.8% will starts … These alloys consists carbon in form graphite flakes, which are surrounded by … Pearlite is the eutectoid mixture of ferrite (87.5%) and cementite (12.5%).

Such surface tilting is further evidence for a shear-like transformation, but the orientation relationship between austenite and bainite is not necessarily the same as that between austenite and martensite. In fact, the ...

Web$\begingroup$ @user586228 - We use 0.76%, because that is the 100% pearlite line. To the left is a mix of pearlite and ferrite $\alpha$. To the right is a mix of pearlite and ledeburite. 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.
