Hydrogen Embrittlement of Metallic Materials in Corrosive Environments

Abstract

This paper describes the outline of hydrogen embrittlement（HE）of metallic materials in corrosive environments in terms of corrosion reaction, entry and penetration of atomic hydrogen, the effects of atomic hydrogen on material properties and HE mechanisms already reported. In addition, the issues on HE in corrosive environments and a unified concept of HE mechanism are also discussed.
