Special Issue Information
Dear Colleagues,
The processes of additive manufacturing (AM) offer a range of processing conditions that are highly interdisciplinary and complex. Among these is solidification of metallic alloys and ceramics that are deposited using direct energy systems. The final microstructure and hence properties of the built component is dependent on numerous variables including the type of alloy, the method of AM processing, the dwell time between passes, in situ cooling, and the size of the component. These variables also affect the bonding between each layer and the degree of metastability and aging (layer by layer) that a microstructure has following each build.
This Special Issue will focus on solidification and liquid phase sintering characteristics in AM, the evolution of microstructure of the component as it is built. The degree of metastability and its evolution as the component is built is of interest, as are the resultant mechanical properties. Both experiments and modelling efforts are encouraged. Of particular interest are in situ measurement techniques that quantify the thermal and solidification history of the part as it is being built, and how these result in mechanical properties. Additionally, in situ deformation or other novel process steps following deposition and how these affect structure, and subsequent mechanical properties are of interest.

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.
