Microstructural Engineering in Powder Metallurgy and Additive Manufacturing Alloys

Dear Colleagues,

The microstructural features of alloys fundamentally determine their mechanical, functional, and environmental performance. Recent advances have underscored the transformative role of processing methods such as powder metallurgy and additive manufacturing in engineering superior microstructures that elevate alloy strength, ductility, fatigue resistance, and thermal stability. For instance, tailored microstructures in alloys by casting and pulvimetallurgy innovations, alloy chemistry adjustments, and heat treatment have significantly improved the mechanical behavior.

Mechanical alloying, sintering methods, and phase transformations in advanced alloys are providing new routes to lightweight, robust, and thermally stable materials. In parallel, the integration of data-driven approaches and machine learning is accelerating alloy design, enabling more efficient prediction and optimization of microstructure–property relationships.

This Special Issue invites but is not limited to contributions across these evolving dimensions: microscopy to property correlations, innovative alloy system development, eco-conscious composite fabrication, and the interplay of modeling and cutting-edge manufacturing routes. We aim to provide a platform that reflects current research trends and helps guide material scientists and technologists toward the next generation of alloy design.

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.
