Abstract Scope |
Hydrogen uptake in metals is of concern across a wide range of industries since these materials then become susceptible to embrittlement, stress corrosion cracking, fatigue, and other material property concerns. Our work explores the effect of varying impurity concentrations on hydrogen uptake rates and localized mechanical properties. This effort is investigated by combining Sieverts’ apparatus and nanoindentation testing on Ti of varying purity to evaluate the mechanical properties of various titanium samples with specific hydrogen loadings. Importantly, the utility of nano-scale mechanical testing could reveal critical details like the hydrogen spatial distribution and subsequent variation in material properties. |
