Dear Colleagues,

In the context of the increasing use of advanced metallic materials in the chemical, transportation, and aerospace industries—with the hope of meeting the demand for energy-efficient and environmentally benign engineering systems—achieving balance between the mechanical properties of formability, strength, and hardening capacity remains a challenge. We wish to examine this in our Special Issue, for which the scope covers plastic deformation and metal plasticity, which include the preparation of advanced metallic materials, microstructural characterization and properties measurement, and plastic deformation mechanisms analysis. Even though plastic deformation is associated with the mechanical properties and constitutive response of metallic materials, the microstructure, composition, and their size or distribution control the various deformation mechanisms that determine the strengthening, hardening, and toughening behaviors. Therefore, the use of alternative preparation methodologies is encouraged to successfully prepare novel advanced metallic materials, such as nanotwinned metals, gradient-nanostructured metals, bi/multi-modal nanostructured metals, suprananostructured metallic materials, etc. Novel nanostructured metallic materials allow the various deformation mechanisms to simultaneously affect plastic deformation in the metallic materials, leading to the possibility of designing materials with specific mechanical properties. From these perspectives, multi-scale characterization and theoretical analysis play the essential role in exploring the plastic deformation behavior and capturing the microstructure–property relation in novel advanced metallic materials.

In this Special Issue, we welcome articles that focus on the preparation methods for advanced metallic materials, microstructural characterization for plastic deformation, the relationship between microstructure and mechanical properties, multi-scale simulation and constitutive modeling for plasticity, and deformation mechanism analysis in experiment and in theory. Plastic deformation and plasticity in extreme conditions is an area of particular interest, with potential for implementation of advanced metallic materials in high-performance products under extreme environments.

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.
