Fig. 3
Analysis and visualization of defect evolution in W and WTaCrV HEA with 2% He atoms inserted, under overlapping cascade simulations: (a) Concentration of Frenkel pairs as a function of dose. (b) Maximum size of interstitial clusters as a function of dose. (c) Maximum size of vacancy clusters and He clusters as a function of dose. Fraction of interstitials in different cluster size ranges as a function of dose in (d) WTaCrV HEA and (e) W. Fraction of vacancies in different cluster size ranges as a function of dose in (f) WTaCrV HEA and (g) W. Visualization of defects at 0.2 dpa for (h) WTaCrV HEA and (i) W: one frame displays vacancies (blue), interstitials (red), and dislocations (green for ½ < 111 > loops and pink for < 100 > loops), while another frame shows the positions of He atoms (light blue).
