    Graduate Student Project: IRRADIATION DAMAGE OF FE-10%CR STRUCTURES UNDER PRESSURE USING MD SIMULATION The objective of this work is to study the defects generation process for models of Fe-10%Cr under pressure using molecular dynamics (MD) simulation technique. Models of Fe-10%Cr have been built using a concentration dependent interatomic potential (CDM). The models have been stressed using three different types of applied pressures: uniaxial, biaxial, and hydrostatic. For each case, seven different pressure values between -10000 to +1,0000 bars have been tested under the application of PKA energy between 2-10 keV. The produced point defects have been identified using the Wigner-Seitz method. The number of produced point defects increases with increasing the primary knock-on-atom (PKA) energy in all cases. For models under biaxial and hydrostatic pressures, the produced point defects show a power relationship in both tension and compression regions. The Cr atoms energetically favor interstitials positions over vacancies positions. The percentage of Cr in interstitials positions is higher in all cases and more than the initial alloy matrix percentage.
