A phase-field modeling of void swelling in the Austenitic stainless steel
Chang, Kunok,Lee, Gyeong-Geun,Kwon, Junhyun GORDON & BREACH / HARWOOD ACADEMIC PUBLISHING 2016 RADIATION EFFECTS AND DEFECTS IN SOLIDS Vol.171 No.3
<P>Two-dimensional phase-field simulations of void swelling in the Austenitic stainless steel were performed for irradiated materials. A numerical model was established for void swelling with an implementation of the elasticity effect, and we examined the roles of the applied stress and grain boundary sink strength and Frenkel defect recombination in determining the void swelling rate. The obtained results were compared with the existing experimental observations.</P>
Comparison of the primary damage states in iron and nickel by molecular dynamics simulations
Kwon, J.,Kim, W.,Hong, J. -H. GORDON & BREACH / HARWOOD ACADEMIC PUBLISHING 2006 RADIATION EFFECTS AND DEFECTS IN SOLIDS Vol.161 No.4
<P> A displacement cascade formation in bcc-Fe and fcc-Ni has been investigated by using molecular dynamics (MD) simulations and improved many-body interatomic potentials. To assure the statistical validity of the calculation, multiple simulations are required at identical conditions. Six cascade simulations were run in the following two cases, with simulation energies of 3.5 keV at 100 K and 4.1 keV at 570 K. The cascade simulations for bcc-Fe were carried out by using the MOLDY code and the interatomic potentials developed by Finnis and Sinclair, whereas those for fcc-Ni were conducted by using the MDCASK code and the embedded-atom method potentials. The MD calculations demonstrate that the atomic configurations of the primary damage state are similar in Fe and Ni. However, the bcc-Fe displacement cascade produced more residual defects than the fcc-Ni cascade. In addition, various sizes of interstitial clusters are observed in Ni. As these parameters have important implications for the assessment of a radiation damage to materials, we derived the primary damage parameters for a future use in the kinetic models.</P>
