Topical Collection Information

Dear Colleagues,

We are witnessing significant progress in the study of alloys, both “conventional” and “advanced”, namely ferrous and light metal alloys, superalloys, high entropy alloys, complex concentrated alloys, alloys for ultra-high temperatures, refractory metal alloys, and metallic glasses, for a wide range of structural applications. Alloys with simple or complex compositions and microstructures are processed using liquid route or solid-state processing methods, for example casting, directional solidification, clean melting, floating zone melting, additive manufacturing, rapid solidification, forging, rolling, extrusion, and isostatic pressing.

The design and development of alloys to meet property targets requires an understanding of processing and how the latter influences the resultant microstructure and mechanical properties. This naturally leads to researching the fundamentals of processes with experiments and modelling.

This collection will present the latest research into various classes of alloys, processed using liquid route and solid-state metallurgical operations, and will include research focusing on the complex chemistry of some modern alloys. Research about alloy mechanical properties will be presented as well as research on process-microstructure–property relationships.

The collection could publish research articles along with short communications, and review articles. Papers that are closely aligned to metallurgy, material science, and mechanical engineering that consider processing, microstructures, mechanical properties, and structure–property relationships are welcome, for example, research about the crystal growth of intermetallics. The research papers submitted to our collection should contain novel experimental, modelling, or theoretical results that can influence and motivate the metallurgical research community.

Topics of interest include, but are not limited to:

  • Theoretical, modelling, and experimental research on alloy solidification;
  • Research on alloy deformation;
  • Research that addresses process-microstructure-property relationships;
  • Theoretical, modelling, and experimental research about mechanical properties of alloys, for example compressive, tensile, impact, hardness, fatigue, toughness, creep properties;
  • Research linking the design and development of new alloys with processing and mechanical properties.

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 collection 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. Alloys is an international peer-reviewed open access quarterly 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 1000 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.

Aluminum–copper alloys have garnered significant attention in modern engineering applications due to their exceptional strength-to-weight ratio, corrosion resistance, and thermal conductivity properties. This study investigates the tribological performance optimization of Al10Cu alloys through chromium coating deposition, focusing on coefficient of friction and mass wear analysis in dry sliding conditions. Cr-coated Al10Cu alloys were fabricated through powder metallurgy and electrodeposition techniques, with comprehensive tribological characterization performed using scanning electron microscopy combined with energy-dispersive X-ray spectroscopy, X-ray diffraction analysis, microhardness measurements, and dry sliding wear testing. The chromium coating exhibited exceptional surface hardness of 720.9 HV, representing a remarkable 15-fold improvement over the uncoated Al10Cu matrix hardness. Tribological evaluation demonstrated outstanding wear resistance with the Cr-coated Al10Cu system achieving only 0.10 mg mass loss compared to 0.55 mg for the uncoated alloy, representing an exceptional 81.8% reduction in material removal. Despite a nominal increase in the coefficient of friction from 0.618 to 0.733, the chromium coating effectively transformed the wear mechanism from severe material removal to a controlled mild wear regime. The results establish the Cr-coated Al10Cu system as a highly effective solution for applications requiring extended operational lifespans under dry sliding conditions. Full article
