Special Issue Information

Dear Colleagues,

Recent changes in international policy, particularly in the European Union, have sparked innovative research in energy conversion technologies. These technologies are useful in a wide range of applications including environmentally friendly refrigeration, non-pneumatic precision actuation, magneto-mechanical energy harvesting, and thermomagnetic or magneto-mechanical sensing. Thus, multifunctional shape memory alloys (SMAs) are ideal candidates for these energy conversion systems and have shown promise for solving these novel complex problems.

The future perspective of SMA applications is exciting, particularly due to their high coefficients of performance (COPs) and energy conversion efficiencies. However, one of the main prerequisites for their future success is improved mechanical properties. Recent developments have led to the discovery of NiCoMnTi magnetic shape memory alloys that exhibit excellent mechanical properties in combination with meta-magnetic transitions. It is my hope that further microstructural design in magnetic SMAs will lead to new structure–property relationships that will further expand their application envelopes and pave the way for the development of commercialized energy conversion systems.

This Special Issue of Metals focuses on the structure-property relationships in magnetic shape memory alloys. The papers presented in this Special Issue give an account of the recent developments in microstructural engineering and processing, which yield improved mechanical and magnetic properties in all alloys that exhibit reversible martensitic phase transitions (see the Keywords/Topics below). Your contribution is highly valued and appreciated. We invite you to contribute research that studies the effect of processing on the structure of novel SMAs and the resulting magnetic and mechanical properties.

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.
