Special Issue Information
Dear Colleagues,
The recent increase in industrial and commercial development has significantly increased the demand for metals with mechanical properties superior to those of conventional alloys. High-entropy alloys (HEAs), defined by their multi-principal element composition, have demonstrated remarkable properties such as enhanced thermal stability, high hardness and strength, excellent ductility, and exceptional resistance to wear and corrosion. More recently, medium-entropy alloys (MEAs) have emerged as promising alternatives. MEAs offer a balance between performance and density, exhibiting improved mechanical properties, lower weight, and, in some cases, superior corrosion resistance and thermal stability compared to both conventional alloys and HEAs. These attributes make these alloys highly attractive for critical applications in the automotive, aerospace, and power generation sectors, spurring intensified research efforts to optimize their composition, microstructure, and functional performance.

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. Lubricants 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.
