(a) State THREE (3) solubility categories of the phase diagram. (b) By referring to the Iron-Carbon phase diagram in Figure 2; (i) Determine the maximum solubility of carbon in a iron (ferrite) and in y-iron (austenite). (i) Calculate the percentage of phases (a and y) present at 728°C for 0.5%wt carbon. (iii) Sketch the phase(microstructure) as your answer b(ii).
