High-sensitivity hydrogen gas permeation: system development, sample preparation, and influence of testing variables
R. Li, A. Zafra, Z. D. Harris +1
There is a need to develop quantitative, high-resolution hydrogen gas (H2) permeation techniques to provide a better understanding of hydrogen-material interactions. This study aim…
New insights into hydrogen-assisted intergranular cracking in nickel
S. Quan, A. Zafra, E. Martínez-Pañeda +3
We characterize the grain boundary (GB) susceptibility to hydrogen-assisted intergranular cracking in pure nickel as a function of coincident site lattice value (-n), over a wid…
TDS Simulator: A MATLAB App to model temperature-programmed hydrogen desorption
E. García-Macías, Z. D. Harris, E. Martínez-Pañeda
We present TDS Simulator, a new software tool aimed at modelling thermal desorption spectroscopy (TDS) experiments. TDS is a widely used technique for quantifying key characteristi…
Hydrogen embrittlement susceptibility of additively manufactured 316L stainless steel: influence of post-processing, printing direction, temperature and pre-straining
G. Álvarez, Z. Harris, K. Wada +2
The influence of post-build processing on the hydrogen embrittlement behavior of additively manufactured (AM) 316L stainless steel fabricated using laser powder bed fusion was asse…
On the relative efficacy of electropermeation and isothermal desorption approaches for measuring hydrogen diffusivity
A. Zafra, Z. Harris, E. Korec +1
The relative efficacy of electrochemical permeation (EP) and isothermal desorption spectroscopy (ITDS) methods for determining the hydrogen diffusivity is investigated using cold-r…
Comparison of hydrogen diffusivities measured by electrochemical permeation and temperature-programmed desorption in cold-rolled pure iron
A. Zafra, Z. Harris, C. Sun +1
The diffusivity of hydrogen in cold-rolled pure iron is investigated using permeation and desorption methods. Electrochemical charging, electro-permeation and thermal desorption sp…
On the suitability of slow strain rate tensile testing for assessing hydrogen embrittlement susceptibility
Emilio Martínez-Pañeda, Zachary D. Harris, Sandra Fuentes-Alonso +2
The onset of sub-critical crack growth during slow strain rate tensile testing (SSRT) is assessed through a combined experimental and modeling approach. A systematic comparison of…
