Study of Microstructure and Irradiation Damages in Metals and Alloys—2nd Edition

Dear Colleagues,

The development of advanced nuclear systems, including fusion reactors, generation-four fission reactors, accelerator-driven subcritical nuclear systems, accident-tolerant fuel reactors, etc., calls for irradiation-resistant materials. Under the irradiation environments of these nuclear systems, severe damage may occur in the structural materials, mainly metals and alloys, which would degrade the mechanical properties and/or accelerate corrosion behavior. Irradiation induces various kinds of defects, including dislocation loops, cavities, and precipitates, as well as bubbles formed by transmutation-induced or injected helium and hydrogen (or deuterium/ tritium). Investigation of the mechanism of defect evolution and of the response of different structures to irradiation conditions is of great importance for understanding irradiation behavior and promoting the development of advanced irradiation-resistant materials.

For this Special Issue, we seek articles that cover a wide range of various aspects concerning the microstructure and irradiation damage of metals and alloys. The idea is to show how various irradiation parameters affect the formation and evolution of defects, and how various structures of metals and alloys respond to irradiations. Articles on irradiation damage, including the characterization of irradiation-induced defects, computer simulations of the mechanism and evolution of defects, and on the effect of irradiation defects on mechanical properties are welcome. Also of interest are articles that employ, among other techniques, electron microscopy, positron annihilation spectrum, small-angle X-ray/neutron diffraction, X-ray absorption spectroscopy and other experimental characterization methods, as well as first-principle calculation, molecular dynamics simulation, kinetic Monte Carlo simulation, cluster dynamics simulation, rate theory simulation, and other simulation methods to investigate neutron/ion-beam/electron-beam irradiation of metals and alloys.

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. Metals 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.
