Special Issue Information

Dear Colleagues,

Laser processing of metals and alloys enables high precision, efficiency, and flexibility. At the same time, it enables innovative functionalities of workpieces that meet the current requirements of ecology and digitalization. These include welded lightweight car bodies, the welding of copper-based electrical components, the microstructuring of surfaces for high-strength and airtight hybrid components, and many others. All of these functionalities are the result of the unique properties of laser light, which can be focused on an extremely small area and achieve ultra-short interaction times.

This Special Issue aims to present research and development results in the fundamentals and applications of laser processing of metals and alloys. Topics of interest include laser processing of advanced materials for electromobility, energy storage, tribology, and medicine. It covers a wide range of technologies, such as proven welding, cutting, and drilling, as well as advanced laser-based 3D printing, micro- and nanostructuring, and cleaning processes. In addition, the development of new laser processing systems, process monitoring, and real-time control are also very welcome.

I am pleased to invite you to submit a manuscript to this Special Issue. Full papers, short communications, and reviews are very welcome.

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 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.

The improvement of PBF manufacturing accuracy has been an urgent problem to solve. The columnar-to-equiaxed transition of rapid solidification during laser powder bed fusion (L-PBF) has been reported, while its influence on the accuracy and surface roughness of fabricated 316L micro-lattice structures remains to be studied. This study presents a novel fully coupled finite volume method for cellular automata (CA), integrated with response surface methodology (RSM), which is applied to investigate the columnar-to-equiaxed transition influence on the accuracy and surface roughness of ultra-precision additive manufactured 316L lattice structure by L-PBF. It is proven that the higher overlap is identified as the optimal strategy for improving both surface quality and dimensional accuracy. Both the CA model prediction and the experimental results reveal that the effect of latent heat releases from the grain refinement on the adhesion of the surrounding powder is an increment of the surface roughness, while the decrement of the surface quality and accuracy. The overlap strategy is promoted to be the most suitable measure to achieve both high surface quality and manufacturing accuracy. The surface roughness Ra (SP) can rapidly decrease by 68.6%, and the mean diameters decrease by 18.7% under the overlap strategy. Full article
