Special Issue Information

Dear Colleagues,

Titanium alloys are widely used for applications requiring an excellent mechanical resistance and high strength at elevated temperature. These alloys have high mechanical characteristics that allow better performance in commercial aircraft, and a significant gain compared other materials.

In manufacturing production, titanium alloys are classified as hard to cut materials. The main problems encountered when machining these materials are the low material removal rate and the short tool life because of the excessive wear exhibited during the chip formation process. The first findings of machining titanium alloy are manifested by low cutting speeds. This causes high cycle times and reduced tool life, and then generates an increase in manufacturing costs. In view of all this, productivity gets affected; increasing productivity is a big challenge and needs the good understanding of the mechanism of material removal

This Special Issue concentrates on recent machinability studies (theoretical and experimental) involving cutting forces, surface roughness, cutting temperature, tool-wear, coating, chip formation process, microstructure and any other machinability parameters aimed at improving the machinability of titanium alloys.

Recently, there has been a growing interest and tendency to employ more friendly processing techniques to play a key role in performing successful and efficient machining operation. Significant advances have been made in understanding the cutting tools, machine controls, different machining methods, and also in understanding the cooling/lubrication effect when machining at higher cutting conditions from practical and theoretical stand points. Research articles focusing on these developments that have particularly enhanced the machinability of titanium materials are encouraged as well.

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. 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 1000 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.
