Special Issue Information

Dear Colleagues,

Hydrogen plays a pivotal role in decarbonising sectors in which emissions are difficult to remove, including heavy goods vehicles, maritime, aerospace and power generation, etc. This will not only increase the demand for clean hydrogen production but also promote material development across the hydrogen supply chain, from improving hydrogen generation infrastructures, to designing large hydrogen storage systems and fast hydrogen transportation networks, as well as employing hydrogen as an energy vector. Metals are widely utilized across these applications, and it is critical to understand how hydrogen may affect their structural integrity under existing and new operating environments.

In this Special Issue, we welcome submissions on the fundamental and applied research of Hydrogen Embrittlement in Metals, with the aim of addressing known challenges relating to structural components of the hydrogen supply chain. Topics on the mechanisms of hydrogen-related mechanical degradation, hydrogen adsorption, diffusion, and trapping, as well as on the development of novel hydrogen-tolerant materials are welcome. Studies based on the development of multi-scale experimental and/or simulation methods are particularly encouraged.

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. Metals 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 2600 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.

Hydrogen embrittlement (HE) poses the risk of premature failure for many metals, especially high-strength steels. Due to the utilization of hydrogen as an environmentally friendly energy source, efforts are made to improve the resistance to HE at elevated pressures and temperatures. In addition, applications in hydrogen environments might require specific material properties in terms of thermal and electrical conductivity, magnetic properties as well as corrosion resistance. In the present study, three high-strength Cu-base alloys (Alloy 25, PerforMet® and ToughMet® 3) as well as austenitic stainless AISI 321, Ni-base alloy IN 625 and ferritic steel 1.4511 are charged in pressurized hydrogen and subsequently tested by means of Slow Strain Rate Testing (SSRT). The results show that high-strength Cu-base alloys exhibit a great resistance to HE and could prove to be suitable for materials for a variety of hydrogen applications with rough conditions such as high pressure, elevated temperature and corrosive environments.
