Microstructure and Properties of Intermetallics

Dear Colleagues,

Intermetallic compounds can exhibit many excellent properties vastly different from those of pure metals or their alloys—for example, high melting points; high thermal conductivity; low densities; great strength; good oxidation resistance; low ductility; and brittle fracture at room temperature. Moreover, intermetallics possess strong stability at high temperatures. Therefore, they can compete with and surpass conventional metallic materials in highly demanding structural applications in such key fields as the automotive, aeronautic, energy, and transport sectors.

A deeper and more fundamental understanding of the microstructure evolution mechanism would accelerate the improvement of mechanical properties and processibility of intermetallics. Research development of such alloys over the years primarily focused on the refinement of the microstructure and improvement of properties through compositional optimizations and the application of various processing technologies.

The main groups into which intermetallics can be classified are: nickel aluminides, iron aluminides, titanium aluminides and others such as silicides, nickel titanium, and refractory metal aluminides.

The aim of this Special Issue is to present a review of the latest advances in the various aspects of microstructure and the various properties of intermetallics. We welcome contributions on topics that include, but are not limited to:

• Intermetallics
• structure characterization
• Additive Manufacturing
• Phase transformation
• stability and ductility
• Heat treatment
• corrosion and oxidation
• Strengthen

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. 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.
