Special Issue Information
Dear Colleagues,
Metals and their alloys are the major workhorse materials in terms of industrial and structural applications, and—largely because they exhibit high levels of deformability that permit arbitrary changes of shape without cracking—continue to remain irreplaceable even today. Recently, heterostructured (HS) materials have been emerging as a major research field because of their superior properties and excellent application potential. Hetero-deformation induced (HDI) strengthening and HDI hardening are responsible for the superior mechanical properties of HS materials, and are major factors determining their mechanical behavior, adding to conventional dislocation-based strengthening and hardening to provide additional enhancements of strength and ductility. In addition, grain boundaries and interphase interfaces in metals have been shown to play a fundamental role in material properties such as strength, fracture resistance, work hardening, and damage evolution. In particular, heterophase interfaces play a crucial role in deformation microstructures and thus govern the mechanical properties of multilayered composites.
Potential topics include, but are not limited to:
- Heterogeneous lamella structures;
- Layered structures;
- Gradient structures;
- Dual/multiple phase structures;
- Harmonic structures;
- Bi-modal structures;
- Metal matrix composites, etc.
We look forward to receiving your contributions.

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. Nanomaterials 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 2900 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.
