3. The following true stress-strain curves were obtained from room temperature tensile testing of dogbone specimens of irradiated Inconel 718. Answer the following questions as related to this data. 1200 1100 1000 2x 900 3 x 800 700 4 x 600 500 400 300 200 100 0 0.00 0.05 0.10 0.15 0.20 0.25 Strain Stress (MPa) MEEN 360: HW #11 Due by Wednesday. 11:59 pm. (a) Imagine that these samples (1-4) were the same except that they were irradiated to different extents. Which sample received the largest dose of irradiation? Also, what microstructural changes occurred during this large dose of irradiation? (b) Imagine that these samples (1-4) represent samples irradiated under identical conditions (i.e., dose and time). However, they were simultaneously heated at various temperatures (200C, 300C, 400C, and 500C) during irradiation. Which sample was heated to the largest temperature (500C) during irradiation? (c) Imagine that these samples (1-4) represent samples irradiated under identical conditions. However, after irradiation, they were heated at 500 C for different amounts of time. Which sample was heated for the longest time? Also, what microstructural changes occurred during this heating to 500 C (for the longest time)
