Special Issue Information
Dear Colleagues,
Shape memory alloys (SMAs) are unique class of metallic smart materials, that show the ability to recover large deformations. The memory characteristic of these alloys is the result of a solid-state diffusionless phase transformation, also known as martensitic transformation. The phase transformation in SMA can be induced by the application of mechanical stress or temperature. Magnetic shape memory alloys can display a similar behavior by the application of a magnetic field. The martensitic transformation and associated shape memory response in SMAs are highly affected by the chemical composition and microstructure of the alloy. The sensitivity of SMAs to these factors provides the opportunity to enhance and tailor their strength, recovery ratio, cyclic stability as well as adjusting their phase transformation temperatures for desired applications through a variety of pre and post-fabrication treatments. Given their tremendous advantages, SMAs are currently being employed in some advanced structural pseudoelastic applications, actuation systems, damping systems and are continuously studied for new applications as well.
This special issue is for the most recent advances in all aspects of traditional, high-temperature, and magnetic shape memory alloys. All advancers with contributions from manufacturing, post-processing treatments, alloying, experimental and theoretical mechanics, and physics are welcome. The studies to gain an in-depth understanding of shape memory alloys due to fatigue, fracture, and environmental factors are invited. The novel applications of SMAs in all areas including bio-medical devices, actuators, thin films, robotics, aerospace engineering, civil engineering structures, and micro-electromechanical systems (MEMS) are also of interest to this special issue.

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.
