forms because the composition of austenite (0.83 %wt C) is different from either of ferrite (0.025 wt% C) and cementite (6.70 wt% C), and the phase transformation requires that there be a redistribution of the carbon by diffusion. • Subsequent cooling of the pearlite from point B will produce relatively insignificant microstructural changes.
