Titanium Alloy and Titanium Matrix Composite

Dear Colleagues,

Titanium alloys and titanium matrix composites play an increasingly important role as structural materials in the automotive and aerospace fields due to their excellent specific strength, good corrosion resistance, outstanding specific modulus, terrific high temperature strength, and high biocompatibility. The methods for fabrication of titanium and titanium matrix composites include ingot metallurgy, powder metallurgy and additive manufacturing routes, etc. Nevertheless, the preparation of high-performance titanium and titanium matrix composites is still a great challenge, not only due to their inherent poor formality, but also due to the incorporation between ceramic reinforcement/precipitation and titanium matrices, which has become a bottleneck in developing high-performance alloys and compounds. Determining how to design titanium alloys and titanium matrix composites to achieve an optimum combination of strength and toughness is thus an ongoing and fascinating challenge, and it is significant to develop credible design and forming methods. The past decade has witnessed robust momentum in the development of hybrid configuration structures and advanced forming methods, which effectively improve advancements in tensile strength, creep, and fatigue properties. In addition to the existing efforts in realizing application-worthy design and fabrication methods, growing interest in bioinspired and rapid solidification (additive manufacturing) is expected to continue. The present Special Issue on “Titanium Alloys and Titanium Matrix Composites” may become a status report summarizing the progress achieved in the last five years.

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 250 words) can be sent to the Editorial Office for assessment.

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. Crystals is an international peer-reviewed open access monthly 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 2100 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.
