Special Issue Information

Dear Colleagues,

Over the last few years, metal additive manufacturing (MAM) or metal 3D printing has been intensively studied and increasingly the technology has been applied to many industries. Many important challenges remain including the printability of many industrially important alloys and the wider usage of MAM parts in critical loading situations. A determining factor for the printability and properties of MAM parts is the manner of how grains grow and how microstructures evolve under the complex thermal or thermomechanical conditions of MAM. Recently, there has been a strong research effort to understand and control microstructure formation and evolution during MAM of various alloys and to understand how MAM grain growth, particularly grain orientation, affects mechanical properties. In parallel, alloy modification and alloy development for MAM have been well recognized to be necessary and a part of the overall effort of overcoming the challenges of MAM. Thus, this Special Issue of Crystals will focus on the recent studies, experimental and computational, of the important issue of MAM: grain growth and microstructure evolution during both MAM process and post MAM heat treatment and how these MAM-specific microstructures relate to properties.

This Special Issue is particularly concerned with, but not limited to, the topics outlined in the keywords. We sincerely hope you can submit to this Special Issue and to make a contribution to this important aspect of MAM.

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 papers will be 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. 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 1800 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.
