Primary Radiation Damage of BCC Iron under Uniaxial and Hydrostatic Stress: MD Simulation

Article Preview

Abstract:

In this paper we have studied primary radiation damage in body-centered cubic (BCC) Fe under the strain. Molecular dynamics method has been used to simulate atomic displacement cascades of the energy of 10 keV for the initial crystal temperature of 300 K. The strain has been simulated with tensile and compressive stress of 0.25 and 2.5 GPa. We have considered the hydrostatic and uniaxial loadings along the [100], [111], [112] and [210] directions. The average number of produced Frenkel pairs has been evaluated. Also, we have studied clustering of point defects and crystallographic orientation of interstitial configurations. The obtained results show a good agreement with the data reported earlier.
