摘要
到目前为止,关于金属氢脆已进入了很多研究,然而对其表述的所有理论和实验结果的共同特征的,在金属内较低能最位置富集的氢达到一临界浓度就可以萌生微裂纹。因此,为研究氢脆问题,了解关于氢扩散和捕集机制是十分重要的。本文评述了自四十年代发展起来的氢陷阱理论和实验技术。
There are large amounts of researches performed on hydrogen embrittlement in
metals.However,a common feature of all theories and experimental results is that a critical con-
centration of hydrogen must be reached at the low potential sites then a microcrack will be initia-
ted.lt is important to know the mechanism of hydrogen diffusion and trapping in metals for
study hydrogen embrittlement The reviews of hydrogen trapping theory and experimental technique
which have been developed since 1940's were made.
