Answer 1

By implementing the laws and principles of Electrical engineering, provide solution to each part by showing the whole calculation part all along with the proper formulas used. Q1. Conduct a phase assessment and microstructure sketch for a 1035 plain carbon steel at (i) 723+oC and (ii) 723-oC. Illustrate the lever rule computation for one phase at each and every temperature. Q2. Conduct a phase assessment and microstructure sketch for a 1095 plain carbon steel at (i) 723+oC, and (ii) 723-oC. Illustrate the lever rule computation for one phase at each and every temperature. Q3. By using your phase assessment from the above problem, find out: (i) The weight % of proeutectoid ferrite; (ii) The weight % of proeutectoid cementite; (iii) The weight % of pearlite; (iv) The weight % of eutectoid ferrite; (v) The weight % of eutectoid cementite.
