Fatigue and Fracture Mechanisms of Advanced Metallic Materials

Dear Colleagues,

Fatigue and fracture remain critical challenges in ensuring the long-term reliability and safety of advanced metallic materials. With the rapid development of additive manufacturing, welding technologies, and novel structural alloys, new opportunities and challenges have emerged in understanding their fatigue and fracture behavior. Moreover, the increasing demand for lightweight, high-strength, and durable materials in aerospace, transportation, and energy applications requires systematic studies that integrate both fundamental mechanisms and practical engineering solutions.

This Special Issue welcomes contributions addressing the processing–structure–property–performance relationships in advanced metallic materials under cyclic loading. Topics of interest include, but are not limited to, the following:

• Fatigue and fracture mechanisms in additively manufactured and welded metallic structures.
• In situ and advanced testing methodologies for characterizing fatigue crack initiation and growth.
• The role of extreme environments (temperature, corrosive media, radiation, etc.) on fatigue resistance.
• Application of machine learning and data-driven approaches in fatigue life prediction and damage assessment.
• Microstructural design concepts, such as transformation-induced mechanisms and novel strengthening strategies, for fatigue performance enhancement.

This Special Issue aims to provide an interdisciplinary forum for advancing both experimental and computational approaches to fatigue and fracture in advanced metallic materials, fostering knowledge exchange and promoting innovative solutions for structural integrity in demanding applications.

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. 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.
