Correlation between Microstructure and Macromechanical Properties in Additive Manufacturing and Welding

Dear Colleagues,

Additive manufacturing and welding are effective means of building materials from micro to macro scale. In particular, additive manufacturing, also known as 3D printing, has attracted a lot of attention because of its ability to build complex parts directly by accumulating materials layer by layer. Welding can enable reliable bonding between dissimilar metallic materials or even metals and ceramics. To date, additive manufacturing and welding technologies have been extensively researched in recent years. Nevertheless, the correlation between microstructure and macromechanical properties is still not sufficiently clear, limiting the performance improvement of additive manufacturing or welding parts. This Special Issue aims to bring together state-of-the-art research results, including but not limited to microstructure formation and macromechanical properties in additive manufacturing or welding, and to help researchers around the world to better track the latest research progress and further advance the development of additive manufacturing and welding together to make high-performance parts.

Potential topics include, but are not limited to:

• Process-structure-performance relationships;
• Microstructure evolution and its formation mechanism;
• Residual stress distribution and its formation mechanism;
• Micro-and macromechanical properties;
• Role of microstructure in mechanical properties;
• Additive manufacturing and welding of high-performance parts;
• Future perspectives for additive manufacturing and welding.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals 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 2100 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.
