Effect of He$sup +$ and D$sup +$ ion beam flux on blister formation in niobium and vanadium
From international conference applications of ion beams to metals; Albuquerque, New Mexico, USA (2 Oct 1973). The effect of incident ion beam flux on the blister formation in annealed polycrystalline niobium and vanadium has been investigated for 0.5-MeV He/sup +/ and 0.25-MeV D/sup +/ projectiles. For the He/sup +/ ions the flux was varied from 1 x 10/sup 13/ ions/(cm/sup 2/-sec) to 1 x 10/sup 15/ ions/(cm/sup 2/-sec), the targets were held at 900 deg C, and the total dose was varied from 0.1 to 1.0 C/cm/sup 2/. For the D/sup +/ ion irradiation ihe flux was varied from 1 x 10/sup 14/ to 1 x 10/sup 15/ ions/ (cm/ sup 2/-sec), the niobium targets were held at 700 deg C, and the total dose was 2.0 C/cm/sup 2/. For both the helium implanted vanadium and riobium the blister density shows a stronger flux dependence than the average blister diameter. For deuteron implanted niobium the blister size increased as the flux was increased from 1 x 10/sup 14/ to 1 x 10/sup 15/ ions/(cm/sup 2/-sec). (auth)
