Special Issue Information
Dear Colleagues,
Hydrogen embrittlement is a phenomenon where, when dissolved in metals, specifically metallic alloys reduce the mechanical strength of the material. Due to its small atomic size, hydrogen diffuses very rapidly even at normal temperatures. The absorbed hydrogen interacts with various material defects, such as vacancies; dislocations; and other microstructural features, such as grain boundaries, which leads to macroscopic failure. The formation of metallic hydrides can also lead to hydrogen-related failure in metallic alloys. Research in this direction is fundamentally important to increase resistance to hydrogen embrittlement in metals due to its applicability in engineering alloys.
This Special Issue will focus on the following topics:
- Hydrogen embrittlement (HE).
- Hydrogen-enhanced localized plasticity mechanism (HELP).
- Hydrogen-enhanced decohesion mechanism (HEDE).
- Hydrogen-assisted fracture (HAF) and hydrogen-assisted cracking (HAC).
- Stress corrosion cracking (SCC) and hydrogen embrittlement (HE).
- Hydrogen interaction with solutes and material defects.
- APT for the atomic-scale characterization of hydrogen in structural materials.
- Causes and effects of hydride formation on crack tips.
- Overview on the challenges and advancements in experimental techniques over the years.
- Hydrogen interaction with microstructural features such as grain boundaries and precipitates.
- The formation of metallic hydrides and their role in hydrogen-related failure.
Other than the mentioned topics, any articles related to hydrogen failure in metals are welcome. These research articles can be based on experimental results, simulation and statistical modeling. Submissions may include either review articles or original research work.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
