Stress-Corrosion Cracking in Materials

Dear Colleagues,

Stress corrosion cracking (SCC) takes place due to the synergistic action of the environment on a susceptible material under tensile loading. SCC promotes the formation of cracks that can propagate, owing to the combined action of stress and environment, with a risk of rupture of structural components even at loads much lower than the tensile strength. Many alloys can exhibit stress corrosion cracking phenomena in unique environments. As a title of example, the susceptibility of high strength steels in the presence of hydrogen recombination poisons is well known in the oil and gas industry. Aluminum alloys—mainly age-hardening alloys—are susceptible to stress corrosion cracking and corrosion fatigue in the presence of chlorides. Copper alloys suffer SCC in ammonium salt environments. Although several studies have been conducted in recent years, a full understanding of such phenomena is far from being reached. In addition, new joining and manufacturing technologies of materials and their effect on the material properties (friction stir welding, additive manufacturing, etc.) open the theme of qualification for the specific environment and application.

The aim of this Special Issue is to give an up-to-date overview of the stress corrosion cracking of materials, covering all its aspects, moving from the design through the mechanism to the qualification of new materials and processes.

Full papers, short communications, and reviews are welcome.

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. Materials is an international peer-reviewed open access semimonthly 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.
