Question

could somebody please answer the question in picture 2 using data in picture 1. and please answer in paragraph format.

UTS Yield Elongation Toughness (ksi) | Alloy and Microstructure Hardness (record which Rockwell scale was used) | (kg) | (%) 0) ( Grain size & Fraction of each Phase) Tensile Charpy Tensile Charpy Grain size RD 0.0322 RD-0.0467 (mm) TD-0.0174 TD-0.016 HRB 66GA Surface 1020 A 639 45.3 38.2 135.5(mm) HRB706707 Interior HB 125.9 114.4 interior Phase(S) | Pearlite 35% | Pearlite 35% Ferrite-65% Tensile Ferrite-65% Charpy | Tensile Charpy Grain HRB 82.988.1 Surface size TD-0054TD-0.0177 (mm)RD-0.00755RD-0.0083 1040 A HRB 833 HB 805 Interion 155142 |interior Phase(S) | Pearlite-30% | Pearlite-80% 92.3 56.0 31.7552 Ferrite 7096 | Ferrite 20% content of the annealed plain carbon steels using the microstructure (Pearlite Estimate the car contains 0.8% C, Ferrite contains 0% C). Is this close to what the sample should be, considering accuracy of the ferrite/pearlite estimate?
