摘要: Abstract In order to study the high-temperature embrittlement related helium from viewpoint of distribution and grain size, ( 7.5 × 10 −6 atomic fraction) was injected into stainless steel treated in various ways, using a cyclotron. Helium retarded tendency towards recrystallization steel, size specimen recrystallized after injection clearly smaller. The appreciable above 650°C, could be classified terms mean diameter helium.
