Special Issue Information
Dear Colleagues,
Alloy materials drive innovation across aerospace, energy, automotive, and advanced manufacturing industries. With growing the demands for high-performance materials suitable for extreme environments, emerging technologies are enhancing microstructural control, mechanical properties, and sustainability.
This Special Issue focuses on three key areas: additive manufacturing (AM), high-entropy alloys (HEAs), and welding technologies. AM offers exceptional design freedom and material efficiency, yet challenges remain in process optimization, defect mitigation, and property consistency. HEAs, known for their complex chemistries and outstanding mechanical properties, are being explored for high-temperature stability and corrosion resistance. Welding technologies are advancing via friction stir welding, hybrid techniques, and laser-based methods to improve the joining of dissimilar or hard-to-weld alloys.
Recent studies have sought highlight microstructure–property relationships, in situ monitoring, phase transformation behavior, and the integration of AM with tailored heat treatments. In addition, machine learning-driven alloy design and process control are accelerating the discovery of new alloys and optimizing processing routes.
This Special Issue welcomes original research and review articles that present novel insights and practical applications in alloy development and processing. Contributions featuring experimental work, modeling, machine learning approaches, or industry-focused case studies are particularly encouraged.

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.
