Dislocation loops and their depth profiles in He+ and D+ ion irradiated nickel

He reemission implanted in metals

“…This is also supported by the observation that little dislocation loops remained in He irradiated Ni above 600°C in Ref. [36]. Accordingly, the bubbles move to the surface from deeper region accompanying volume expansion of bubbles (like boiling of water) as observed in the TEM picture of Fig.…”

“…Materials examined are aluminum (Al), nickel (Ni) and molybdenum (Mo), and data given here are concentrated to He reemission for Ni, because behavior of He in Ni has continuously attracted scientific interests and been one of the most investigated and important subjects [16,17,[35][36][37][38][39][40].…”

The Recovery of Gas-Vacancy-Complexes in Fe Irradiated with High Energy H or He Ions

“…The effect of H and He atoms on the development of defect structures is an important problem for materials used in fusion reactors because these gas atoms promote the growth of cavities 1,2) and dislocation loops. [3][4][5] In addition, materials used in fusion reactors are directly damaged by irradiation of H and He atoms with acceleration energy ranging from eV to MeV level.…”

He bubble formation and emission of He in irradiated Fe

“…The interactions between He and irradiation-induced defects have been previously investigated [1][2][3]. He atoms promote the growth of cavities [4,5] and dislocation loops [6,7], and induce void swelling. These microstructural changes lead to degradation of mechanical properties of materials.…”
