Dear colleagues,

The processing of materials using lasers has grown continuously thanks to the decrease in the price of lasers, a greater understanding of the phenomena involved, and the need to treat new metallic alloys. In general, laser surface treatments (LST) have clear advantages over traditional processes, such as automation and reproducibility. Unsurprisingly, LST involves the largest number of laser workstations sold in the world.

The present issue is intended to offer readers a current and innovative perspective on LST processes, including (but not limited to):

• Advances in engraving and marking;
• Surface hardening using lasers;
• Deformation, residual stresses, and fracture in laser processed materials;
• Effects of laser remelting on metallic surfaces;
• Investigations about cladding on surfaces;
• Cutting-edge athermal processing;
• Microstructural changes in metal alloys by exposure to laser beam.

Publishing your article as open to everyone will increase your citations and allow you to continue your research in optimum conditions.

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. Metals 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 2000 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.
