| Abstract Scope |
Structural components in the fields of H energy applications can be subjected to a wide range of exposure temperatures. Despite extensive research on H embrittlement at near room temperature, the H-induced damage behavior in Ni-based alloys at elevated temperatures remains unknown. Here we study the influence of temperature on H-induced damage mechanisms in a Ni-based Inc. 718 alloy subjected to in-situ tensile testing under gaseous H2 environment up to 600 ℃. The detrimental effect of H on ductility was found to be pronounced at the temperature range from 25 to 400 ℃, whereas such effect is moderate at 600 ℃ for the tested H2 pressure and strain rate. The underlying H-induced damage mechanisms are investigated and discussed. |
