Special Issue Information

Dear Colleagues,

With the progress of laser technology in recent decades, manufacturing in aerospace, biomedical, electronics, and other fields depends more on laser welding and laser additive manufacturing.

More and more new materials, manufacturing processes, and post treatments are being applied to change the microstructure of joints and additive manufacturing constructions, thereby improving mechanical properties and enabling formed components to be applied in harsher working environments. For example, using laser shock peening to eliminate residual tensile stress on the surface of additive manufacturing turbine blades; laser welding assembly technology for additive manufacturing components; laser additive manufacturing and welding of shape memory alloys, etc. These studies are of great significance for the development of laser processing technology.

Therefore, this Special Issue will include (but is not limited to) research on additive manufacturing of metals, ceramics, and composite materials, as well as the welding and post-treatment of related parts. Attention should be paid to the relationship between materials, structure, and 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 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. Materials is an international peer-reviewed open access semimonthly 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.

Owing to the high optical reflectivity of copper powder, the high-performance fabrication of copper alloys in the laser additive manufacturing (AM) field is problematic. To tackle this issue, this study employs the remelting process during laser powder bed fusion AM to fabricate defect-free and high-performance CuCrZr alloy. Compared to the non-remelting process, the remelting process yields finer grains, smaller precipitates, denser dislocations, and smaller dislocation cells. It realizes not only the dense molding of high laser reflectivity powders but also excellent mechanical properties and electrical conductivity (with an ultimate tensile strength of 329 MPa and conductivity of 96% IACS) without post-heat treatment. Furthermore, this study elucidates the influence of complex thermal gradients and multiple thermal cycles on the manufacturing process under the remelting process, as well as the internal mechanisms of microstructure evolution and performance improvement.
