“…To improve the resistance to void swelling, the material is suitably modified by adjusting alloying elements and by subjecting it to thermomechanical treatments. Effects of minor alloying components [2][3][4] on the swelling properties of the steel and also the effect of cold working [5,6] had been investigated earlier. The basic understanding of defect production due to irradiation and their thermal stability would pave the way to gain better insight into macroscopic dimensional changes in the material.…”
