(b) Figure 6 shows the eutectoid portion of FeFe3C phase diagram. In particular for Fe0.35% C alloy, determine (i) the temperature at which austenite first begins to transform on cooling. (ii) the primary microconstituent that form. (iii) the composition and amount of each phase present at 728C. (iv) the composition and amount of each phase present at 726C. (v) the composition and amount of each microconstituent present at 726C. rigure 0 : i he eutectoid portion of the reFeC3C phase diagram. (c) A steel contains 18% cementite and 82% ferrite at room temperature. Evaluate the carbon content of the steel. Is the steel hypoeutectoid or hypereutectoid
