Perlite phase
WebThe pearlite transformation involves the redistribution of carbon followed by a structure change, the martensite transformation involves the structure change alone, and, in contrast, the bainite transformation involves a structure change followed by the redistribution of carbon, which precipitates as a carbide. 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 …
