金属表面下氦泡融合与释放研究
Study of the coalescence and release of helium bubble under metal surface
摘要
Abstract
The behavior of helium bubble under titanium surface at different depths has been studied using mo-lecular dynamics method. The competition of helium bubble release and coalescence was analyzed, and the effects of helium bubbles release at different depths were compared. The results show that the helium bubbles are difficult to grow unlimitedly by coalescence. Release would occur when the bubble attains a critical size. The effect of implantation depth on helium bubble coalescence is that, the greater depth is conductive to the formation of a larger helium bubble with a high helium density. The release of a helium bubble at deeper depth would form a larger protrusion and leave a larger surface pinhole on the metal surface. The surface poles with different sizes were observed in experiments, part of the reason came from the release of helium bubbles at different depths.关键词
