標題: | The role of induced alpha '-martensite on the hydrogen-assisted fatigue crack growth of austenitic stainless steels | 作者: | T.C. Chen S.T. Chen L.W. Tsay |
公開日期: | 六月-2014 | 摘要: | The effects of rolling on the hydrogen-assisted fatigue crack growth characteristics of AISI 301, 304L and 310S stainless steels (SSs) were investigated. In hydrogen, cold rolled specimens with a 20% thickness reduction were found to increase the fatigue crack growth rates (FCGRs) in the 301 and 304L SSs, and to a much lesser extent in the 310S SS. However, enhanced slip was observed for the 310S specimen in hydrogen. Hydrogen-accelerated FCGRs of the 301 and 304L SSs were related with the crack growth through the strain-induced martensite formed in the plastic zone ahead of the crack tip. |
