Helium gas bubble formation in binary and ternary alloys of vanadium irradiated by energetic Ni++ ions
1979
Abstract Simulation experiments involving He implantation and 4 MeV Ni ++ ion irradiation were conducted on three binary alloys of V with 5, 10 and 20% Ti and their ternary alloys with Be or Zr up to 1%. All Irradiated alloys display He bubbles of varying sizes and densities. The effect of the three solutes, Ti, Be and Zr, on bubble formation is to promote nonuniform distribution of bubbles through second phase precipitates. The mechanisms leading to, and the consequence of, close association of bubbles with the precipitates are discussed.
