5. A 300 series austenitic steel in the unirradiated state has a yield strength of 200MPa. After irradiation to 35.7dpa at 408C, the void and dislocation loops were characterized. The void and loop density and diameter are given in the table below. (20 points). By how much does the material yield strength increase due to these defects? Which defect causes greater strengthening? Use the following data
