Dear Colleagues,

The crystal structure and crystal orientation of materials are important characteristic parameters that reflect the microstructure of materials, and directly affect the mechanical and physical properties of materials. At present, the traditional measurement methods of crystal properties include metallography, SEM, EBSD, mechanical properties testing and so on. Although these methods have high accuracy, they cause irreversible damage to the material, and have complex processes, cumbersome operations, expensive equipment, and large space footprint, which cannot meet the needs for rapid and non-destructive testing of the material manufacturing industry. Therefore, it is of paramount importance to explore a non-destructive testing method with good adaptability and rapid acquisition of crystal properties of materials. Furthermore, since polycrystalline, oligocrystalline, monocrystalline, and quasicrystalline materials generally belong to random media, with random orientation or orientation distribution, stray grains, dislocations, and residual stresses, these bring continuous challenges for their non-destructive evaluation.

This Special Issue aims to address this pressing need by inviting researchers and practitioners to share their manuscripts that address new techniques and methods related to the non-destructive characterization of random media composed of crystals, ultimately contributing to improvements in material manufacturing processes and the development of high-performance materials. Potential areas of interest for submissions may include, but are not limited to, the development of novel non-destructive testing techniques, advancements in crystallographic analysis methods, innovations in imaging technologies, and the application of machine learning and artificial intelligence in non-destructive testing. Contributions that demonstrate the practicality, efficiency, and effectiveness of the proposed methods in real-world scenarios will be highly valued.

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. 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 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.
