Focus Issue: Journal of Materials Research
Multiscale Materials Modeling of Interface-mediated Thermomechanical Behavior
Issue Date: July 2021
Submission Deadline: December 1, 2020
Advanced materials are usually comprised with a high density of interfaces such as grain boundaries (GBs), or phase boundaries (PBs). When exposed to extreme environments (stress, temperature, irradiation, corrosive), the performance of these materials can be largely dictated by dislocation-/twinning-mediated plastic flow, phase transformation (PT), phonon transport, and their reactions with the GBs or PBs. However, to date, a clear understanding on how such reactions control the materials’ microstructure evolution and, in turn, their overall performance, is still lacking. It remains challenging to use single-scale techniques to simultaneously resolve the dislocation, twinning, PT, and phonon activation at the atomic scale together with the subsequent interface structure changes (fracture or damage) at the mesoscopic level. To meet this challenge, this Focus Issue provides a forum for discussing recent developments in computational/experimental techniques and their applications to understand the heterogeneous materials’ mechanical and transport behavior across a broad range of length scales. The knowledge gained may be used to support the development of new materials with desired strength, ductility, toughness, thermal-/corrosion-/irradiation-resistance, and even a combination of these resistances.
Contributing papers are solicited in the following areas:
• Atomic/meso/macro/multi-scale material modeling theories, methodologies, and algorithms
• Atomic/meso/macro/multi-scale experimental techniques for microstructure characterization Computer simulations of dislocations, twinning, PT, phonons, and their interactions with interfaces
• Experimental analysis of plasticity, thermal transport, facture, and damage in heterogeneous materials

MANUSCRIPT SUBMISSION
To be considered for this issue, new and previously unpublished results significant to the development of this field should be presented. The manuscripts must be submitted via the JMR electronic submission system by December 1, 2020. Manuscripts submitted after this deadline will not be considered for the issue due to time constraints on the review process. Please select “Multiscale Materials Modeling of Interface-mediated Thermomechanical Behavior” as the Focus Issue designation. Note our manuscript submission minimum length of 3250 words, excluding figures, captions, and references, with at least 6 and no more than 10 figures and tables combined. Review articles may be longer but must be pre-approved by proposal to the Guest Editors via jmr@mrs.org. The proposal form and author instructions may be found at www.mrs.org/jmr-instructions. All manuscripts will be reviewed in a normal but expedited fashion. Papers submitted by the deadline and subsequently accepted will be published in the Focus Issue. Other manuscripts that are acceptable but cannot be included in the issue will be scheduled for publication in a subsequent issue of JMR.
