STUDY OF HYDROGEN DISTRIBUTION AND DIFFUSION BEHAVIOUR IN HIGH PRESSURE HYDROGEN CHARGED AUSTENITIC STEEL BY IMMA
用离子探针研究奥氏体钢中氢的分布与扩散行为

The hydrogen distribution curve along cross-section of austenitic steel 21Cr-7Ni-9Mn-N was obtained quantitatively by IMMA (Ion Microprobe Mass Analyzer) with high pressure hydrogen charging specimen. Thus, the hydrogen sol- ubility and diffusivity may be measured as well as the hydrogen permeability and other parameters may be calculated indirectly. The hydrogen distribution in speci- mens either long-term aged in air or electron beam weld seam after high pressure hydrogen charged was also examined.
