Special Issue Information

Dear Colleagues, 

Hydrogen embrittlement is a phenomenon of material degradation present in many engineering materials (metals and alloys) working under aggressive environments, thereby promoting fracture and compromising their structural integrity at both the macro- and micro-levels. Apart from the classical name of hydrogen embrittlement, many names have been used in the past, such as hydrogen degradation (Panasyuk, Andreikiv) or the dual terms coined by Birnbaum and Gerberich: Hydrogen-enhanced localized plasticity (HELP) and hydrogen enhanced decohesion (HEDE).

This Special Issue seeks work on the following topics (but the Special Issue is not limited to them):

  • Hydrogen embrittlement (HE)
  • Hydrogen degradation (HD)
  • Hydrogen damage (HD).
  • Hydrogen enhanced localized plasticity (HELP)
  • Hydrogen enhanced decohesion (HEDE).
  • Hydrogen enhanced delamination or debonding (HEDE).
  • Hydrogen assisted fracture (HAF) and hydrogen assisted cracking (HAC).
  • Hydrogen transport by diffusion and dislocational dragging.
  • Hydrogenation versus cracking. Coupled effects. Effect of history.
  • Hydrogen and plasticity. Hydrogen and dislocations. Hydrogen trapping.
  • Hydrogen deformation interactions. Role of stress-strain fields.
  • Effect of cyclic loading on hydrogen embrittlement. Hydrogen assisted fatigue.
  • Multiscale approaches to hydrogen embrittlement.
  • Fracture and structural integrity at all scales in a hydrogen environment.
  • Computational approaches to the process of embrittlement or degradation.
  • Microscopic approaches. Fractographic analysis of the damage/fracture process.

Accordingly, this Special Issue is open for the following types of manuscripts covering the topic of hydrogen embrittlement/degradation/damage:

  • original research articles
  • review articles
  • technical reports

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 papers will be 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 1200 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 susceptibility ratios calculated from slow strain rate tensile tests have been employed to study the response of three high-strength mooring steels in cold and warm synthetic seawater. The selected nominal testing temperatures have been 3 °C and 23 °C in order to resemble sea sites of offshore platform installation interest, such as the North Sea and the Gulf of Mexico, respectively. Three scenarios have been studied for each temperature: free corrosion, cathodic protection and overprotection. An improvement on the hydrogen embrittlement tendency of the steels has been observed when working in cold conditions. This provides a new insight on the relevance of the seawater temperature as a characteristic to be taken into account for mooring line design in terms of hydrogen embrittlement assessment.
