Special Issue Information

Dear Colleagues,

Ceramic materials have a complex internal structure and are used in important equipment, such as drilling devices, cutting devices, jet engines, and many others. Examples of such materials include multiphase polycrystals, for example, WC/Co, SiC/Al, and Al2O3/ZrO2. The combination of phases with different properties yields a complex microstructure.

Dynamic phenomena are highly diverse. During high-velocity impact, complex phenomena such as cracks, fragmentation, and phase transformation appear in ceramic–metal composites. The behavior of CMM and the composites of all brittle phases is qualitatively different. Special attention is given to the influence of voids within polycrystalline materials on their performance.

In recent decades, advancements in numerical methods, including theory development alongside the application of high-performance computing, have allowed for the analysis of impact phenomena.

Numerical analysis allows insights into rapid processes that are practically impossible to follow during experiments.

  • Impact of samples, fragmentation;
  • Variable dynamic loads;
  • Imperfections, voids, inclusions in grains, imperfections in grain boundaries;
  • Imperfections in interfaces;
  • Numerical methods (finite element method, meshless methods);
  • Nonlocal methods;
  • Thermal effects, phase transformation.

We warmly invite submissions of full papers, communications, or a review.

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. Materials 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 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.

The aim of this paper is to investigate the mechanism of an electric current-assisted superplastic deformation on 3Y-TZP in an oxygen-lean atmosphere. The experiments were performed with different electric currents in the range of 0~5 A. The results show that the flow stress of 3Y-TZP during the deformation was significantly decreased by the combination of Joule heating and the applied current effect. The microstructures of the deformed specimens were all equiaxed grains without an obvious preferential grain growth. The stress exponent n = 2.05~2.61 suggested that the dominant deformation of 3Y-YZP with/without the electric current was grain boundary sliding at 1400 °C. The activation energy of the deformation which decreased from 465 kJ mol−1 to 315 kJ mol−1 by the electric current indicated that the lattice diffusion of Zr cation during the deformation was enhanced. And the deformation rate of 3Y-TZP with the electric current may be controlled by the grain boundary diffusion of Zr cation. Full article
