Advances in High-Energy Flux Technologies for Metallic Materials

Dear Colleagues,

Methods using high-energy fluxes such as electron and laser beams for processing metallic materials are important technologies. These technologies are driving significant advances in the processing and modification of metallic materials, primarily through techniques that utilize concentrated energy sources such as lasers and electron beams and enable advanced heat metallic materials treatments, leading to new materials with superior properties and complex geometries, additive manufacturing (3D printing), surface engineering and modification, etc. High-energy flux methods are foundational to modern metal additive manufacturing (AM), allowing for the creation of intricate, customized components with minimal waste. Focused high-energy sources are used to modify the surface of existing metallic materials, enhancing performance and longevity without altering the bulk properties. In the laser cladding process, a metallic coating is applied to a substrate using a high-power laser to improve surface hardness and corrosion resistance is applied. In surface heat treatment, for improving mechanical properties such as wear resistance and strength, high-energy flux provides rapid, localized heating and cooling rates, leading to microstructural changes. Other physical methods such as physical vapor deposition (PVD) are used to develop advanced coatings. High-energy flux technologies are also used in synthesizing and stabilizing new classes of metallic materials.

Articles focusing on the review, investigation, and innovations of high-energy flux technologies for metallic materials all welcome to this Special Issue of Metals. Research on electron beam and laser technologies, including additive manufacturing, electron beam and laser welding of metals, surface layer treatment, electron beam remelting and refining, electron beam machining, etc., is expected in this Special Issue. Experimental studies and simulations of high-energy flux technologies for metallic materials are also of interest.

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 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.
