Failure Mechanisms in Metallic Materials

Dear Colleagues,

Metallic materials experience various extreme and complex conditions during their in-service condition. Irreversible deformation behaviours occur during complex conditions, manifested in localised slip, fatigue crack nucleation, short-crack propagation, and ultimate failure events. Recently, understanding their failure mechanisms has become a trending problem in a wide range of environmental, energy and aerospace applications. Significant advances have been made in microstructure-based crystal plasticity modelling and in-situ electron microscopy to quantitatively characterise the origin and evolution of failure events at small scale. Meanwhile, considerable interest has arisen in linking macroscopic properties to material microstructure across different length and time scales. Furthermore, the establishment of frameworks integrating experimentation and modelling to understand complex coupled environmental effects, such as hydrogen embrittlement, extreme high temperature, irradiation damage, and corrosion cracking, is crucial to reveal the physical mechanisms behind phenomena. Therefore, we believe that this Special Issue is currently of practical necessity in order to discover the failure mechanisms of metallic components and to provide guidance for their future design.

Potential topics include but are not limited to:

• Fatigue crack initiation;
• Single- and poly-crystal crack growth;
• Irradiation-induced cracking;
• Thermomechanical cracking;
• Corrosion cracking;
• Fatigue indicator parameter;
• Length-scale-dependent fatigue cracking;
• Phase-field modelling of crack growth;
• Stress-riser-geometry-sensitive cracking;
• Hydrogen-embrittlement-induced crack initiation;
• 3D characterization crack initiation/growth;
• Microstructure-sensitive crack initiation/growth.

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 250 words) can be sent to the Editorial Office for assessment.

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.
