Special Issue Information
Dear Colleagues,
Additive manufacturing (AM) techniques have become widely acknowledged, allowing highly complex mechanical parts to be produced, which are not achievable with traditional manufacturing techniques. One of the major advantages of AM is the possibility to customize the shape and mechanical properties of the component, resulting in more application prospects, such as in aerospace, biomedical, and automotive industries. However, AM processes cause a high variability in the achieved mechanical properties that are closely related to the process parameters.
Indeed, depending on the process parameters, the component may be affected by poor surface quality and several defects (such as porosities, inclusions, and a lack of fusion defects). The microstructure is well affected due to the thermal history experienced by the component during the production process, leading to inhomogeneous and anisotropic features. All these aspects affect the mechanical properties of the final component.
Fatigue failure represents the most common in-service failure of mechanical components, and it is highly influenced by the presence of defects. Research efforts are needed both to improve the quality of the produced AM parts and to develop methodologies to directly account for all the factors that influence the fatigue behaviour. Such developments in the AM techniques and in the design methodologies are highly desirable to ensure a sufficient degree of reliability for AM parts and, as a consequence, to promote their use at an industrial scale.
This Special Issue aims to collect original studies on the fatigue characterization of AM alloys, presenting the experimental fatigue results in relation to process parameters and providing information on failure mechanisms and microstructural features and defects. Papers that compare the fatigue properties of AM and conventional alloys are highly appreciated, as well as those that focus on numerical techniques for fatigue life assessment.

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.
