Special Issue Information
Dear Colleagues,
Titanium alloys are widely used as structural material in fields such as the aero-space industry. They are light-weight materials and, in contrast to other light-weight materials such as aluminum or magnesium, possess a rather high melting point (1670 °C compared to 660 °C for Al or 650 °C for Mg). This high melting point could be the basis for the use of Ti alloys in several high-temperature applications, but the use of Ti alloys is limited to about 500 °C due to their low oxidation resistance. Titanium alloys form a TiO2 layer in oxidizing environments which can protect the component at ambient temperatures (i.e., passivation layer). The TiO2 scale becomes deteriorated at high temperatures, leading to accelerated oxygen diffusion and hence high oxidation kinetics. High material loss rates due to this attack can cause the premature failure of Ti components. Alloy developments have led to some alloys which are capable of withstanding temperatures of up to about 600 °C, but only for a very limited period of time. Such alloying methods also have an impact on the material properties. Surface treatment techniques (i.e., coatings) are a different approach, and have also been employed to enhance the high-temperature oxidation resistance of Ti alloys.
In this Special Issue, all aspects of the high-temperature behavior of Ti alloys will be addressed; potential topics include but are not limited to alloy development, oxidation, corrosion, coatings, modelling, and the effects of atmosphere or environment (humidity, deposits, etc.).

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. Metals 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 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.
