Special Issue Information
Dear Colleagues,
This Special Issue is devoted to the current state of the art in titanium matrix composites (TMCs). As one of the most important metal matrix composites (MMCs), TMCs exhibit high specific strength, elastic modulus, temperature durability, wear resistance, and formability. Recent innovative research has shown that tailoring a reinforcement network distribution that is completely different from the conventional homogeneous distribution can not only improve the strengthening effect but can also resolve the issue of poor tensile ductility in TMCs. Based on the network architecture, for example, a multi-scale architecture, two-scale and laminate network microstructures can further inspire superior strength, creep, and oxidation resistance at elevated temperatures. In addition to microstructural tailoring, advanced fabrication methods have also been developed to produce TMCs with high mechanical performance, for instance, laser additive manufacturing and spark plasma sintering. Furthermore, the hot deformation and post-heat treatment of TMCs have been investigated and have shown great potential in regulating the reinforcement distribution, optimizing the interface structure, and adjusting the grain morphology of Ti alloy matrices. As a result, the mechanical properties of TMCs have been effectively improved, and the trade-off between strength and ductility has been resolved. In this regard, the high performance of advanced TMCs can meet the urgent demands for lightweight application-worthy structural materials and potentially replace nickel-based superalloys at 600-800oC while reducing weight by 45%.
This Special Issue particularly welcomes work related to the fabrication, hot processing, microstructure design and evolution, mechanical behavior, simulation, heat treatment, advanced characterization, and atomic-scale interface study of TMCs. We hope that the high-quality research papers presented in this Special Issue will play a positive role in promoting the rapid development of TMCs.
It is our pleasure to invite you to submit your work to this Special Issue. Research papers, reviews, and communications are welcome.

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. 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).
