Abstract:In order to evaluate the hydrogen embrittlement sensitivity of 4130X material, the effect of curvature radius of the high-steel ring on material failure mode and blasting pressure was firstly carried out, and then the hydrogen embrittlement sensitivity index was evaluated for disc samples with different surface roughness. The test results show that when the curvature radius of the high-steel ring is 0.5 mm, 1.5 mm, 2.0 mm, the material is mostly destroyed by shear. When the curvature radius is greater or equal… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
