| Summary: | 碩士 === 國立臺灣海洋大學 === 材料工程研究所 === 98 === The effects of rolling and sensitization treatment on the hydrogen embrittlement susceptibility (HES) of 304L stainless steel (SS) were investigated. Hydrogen embrittlement susceptibility of the specimen was associated with the loss of notched tensile strength (NTS) in H2S solution. The results indicated the increase in beneficial trapping sites for hydrogen in cold-rolled 304L SS accounted for the high NTS and low HES as compared with other specimens. The lowered trapping sites for hydrogen along with the grain boundary martensite, which provided fast diffusion path for hydrogen in the specimen, resulted in increasing the HES of the sensitized specimen.
