由于空间技术,能源,石油工业和大型发电机的转子用氢冷却[1]等工业发展的需要,氢气氛对钢性能的影响已逐渐为人们所重视。氢引起高强度钢脆化这一现象早已为人们所熟知和重视,称为“氢脆”但早先的研究工作比较偏重“内部氢脆”(Internal hydrogenembrittlement)而对外部氢气氛引起的脆性(Hydrogen environment embrittlement)的研究还较少。本文主要概述由氢气氛引起的氢脆。
Due to the needs of industrial development such as space technology, energy, oil industry and large generator rotor cooling with hydrogen [1], the influence of hydrogen atmosphere on the performance of steel has been gradually paid attention to. Hydrogen-induced high-strength steel embrittlement phenomenon has long been well-known and valued, known as “hydrogen embrittlement” but earlier research work more emphasis on “internal hydrogen embrittlement” (Internal hydrogenembrittlement) and external hydrogen atmosphere caused by the brittleness (Hydrogen environment embrittlement research is still less. This article summarizes the hydrogen embrittlement caused by the hydrogen atmosphere.
