Microstructural evolution of V-4Cr-4Ti during ion irradiation at 200{degrees}C
The results of a transmission electron microscopy (TEM) investigation of the microstructural evolution of V-4Cr-4Ti (Heat no. 832665) that was irradiated with 4.5 MeV {sup 58}Ni{sup ++} ions at 200 {degrees}C are presented. Dose effects were investigated for fluences ranging from 0.5 to 5 dpa. When the irradiation dose was increased, the relative number density of black dots and dislocation loops was nearly constant and accompanied by an increase in the size of the defects. Cavity formation was not observed in any of the specimens, indicating high resistance of the alloy to void swelling at the lower temperature of the experiments.
