Contribution Form

Help expand the hydrogen diffusivity database for structural steels and related materials. Submit peer-reviewed, open-access sources. We review every entry before adding it to the public dataset. This form is still experimental; please send suggestions to Denis@Czeskleba.com and we will make sure your data is added with the text, info, and tags you need.

Submission Flow

Fill out the form below with:

  1. Publication metadata: title, authors, journal, year, DOI, open-access URL, abstract, volume/issue/pages, language, and keywords.
  2. Model definitions: single-point, Arrhenius, or power-law parameters (with valid temperature ranges).
  3. Contact info: name + email for follow-up.

Publication
First name Last name ORCID

Select the diffusion mechanisms or material features investigated in the publication that may influence hydrogen diffusion (e.g., microstructure, alloying elements, trapping, surface effects). Papers may address multiple effects, and precise classification is not required. These tags are used for literature discovery and statistical grouping.

Abstract
Additional notes
Experimental Setup

Use these defaults to describe the general parameters of the diffusion measurements. If you varied one of these in your study, keep the default here and specify the variation per data row below. Most studies will only have one material but if you have multiple different ones, pick one here and then adjust the variations on a per data-series level below. For example if you worked with X65 and CrMoV in one study for some reason, class/grade etc. varies, so adjust this in the data section.

Examples:

  • You measured diffusion as part of other experiments on as-received X80 pipeline steel. You might choose base material (no welding), leave phase blank, and add a Microalloys tag. If you varied V across multiple samples (e.g., 0.01-0.05 wt.%), set it to 0.01 wt.% here and change wt.% per series below.
  • If the material is HSLA S690 and you varied the processing route (quenched vs. thermomechanically rolled), pick one route here and set the other on the specific data row.
Data origin

Select whether you directly measured diffusion coefficients or calculated/simulated them. "Extracted from graph" and "Literature review" should mostly be legacy options, but feel free to provide additional info below.

Data notes
Materials

Select the material class and grade that best match the paper. Add microstructure, phase, processing, and tags to capture the key material context. Chemical composition is optional but highly recommended.

Additional Material Tags

Add additional tags to your material for future filtering. For example, an X65 could be a pipeline steel, structural steel, HSLA, or low alloyed.

Chemical composition

Use 0.02 or <0.1 in wt.% | Remainder is assumed Fe | Leave empty if not applicable

Hydrogen Measurement

Please choose the measurement method and calculation model that best match your paper. If you need an option that is not listed, propose it in the measurement notes.

Measurement notes
Surface Condition

Surface state can strongly affect charging, entry, passivation, and permeability. Please select the appropriate surface condition.

Surface condition notes
Cold Work and Applied Stresses

Plastic deformation and applied stresses can alter trap density, diffusion pathways, and effective diffusivity. Please select the options that best match the experimental setup.

Cold work and stress notes
Data rows (one row per model, single point, or list of values)

Required columns: display name and model type. Pick a fitting name that will be displayed on the curve or in the legend. The first author's last name and year will be included automatically. Don't include a temperature range here, as we can add that dynamically. Do use something like "S690 HAZ" or "Vanadium 0.1 wt.%" or "5% Cr" or "5um Pd coated exit side". Usually this will be something that is varied in the overrides below. Minimum and maximum temperatures are required for Arrhenius and power-law models. Single points and list-of-values rows will derive the range from their data. Arrhenius uses D = D0 * exp(-Q/RT). Power law uses D = A * T^n, where T is the temperature in the unit selected above. List of values means a two-column table (temperature, diffusivity), like you would paste from Excel or CSV. The fields below update based on the model type you select. If a specific row needs different material or composition, open "Changes from defaults (this row only)".
