There is a current trend in the industry, in particular for aeronautic applications, to use lighter materials at higher temperatures. Titanium-based alloys (excluding TiAl intermetallics) are currently limited to temperatures below 500–600 °C for long-term applications (e.g., 10 kh). A major concern for these alloys is their resistance to oxygen embrittlement. Solutions need to be found to limit oxygen dissolution and inward diffusion. Protective coatings have to be developed and tested. Ti, as well as Zr, V or Nb dissolve large amounts of oxygen. The oxidation of Zr-based alloys has been widely studied for nuclear applications. In accidental conditions, these Zr alloys may experience very high temperatures (e.g., 1200 °C) for a short time. Ti-O and Zr-O systems have a lot in common. It is, therefore, of interest to group in a common issue, research works on the high temperature oxidation of both Ti and Zr-based alloys to improve our understanding of O ingress in these alloys and to compare the protection solutions which include the modifications of alloys composition and microstructure, as well as protective coatings. Nb-base alloys can be also of interest.
For this Special Issue, we invite authors to publish research articles or comprehensive reviews on the topics referred to above.

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 papers will be 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 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 1500 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.
