【Abstract】 The representative works from an extensive literature on the helium in metals are reviewed in this paper.The status of researches in this field is summarized with an emphasis on the states of helium atoms in metals, their microscopical distribution and migration, and also their macroscopical effects.The problem of the helium induced brittleness in stainless steels is particularly discussed.Some relevant experimental results obtained by us are also included as examples.更多还原
