Special Issue Information

Dear Colleagues,

Shape memory alloys have a unique shape memory effect and superelasticity stemmed from recoverable martensitic transformation, which have been widely used in aerospace, medical implants, mechanical drives and other fields. To date, an increasing number of researchers have paid more attention to the present shape memory alloys with temperature sensing and intelligent driving.

To further widen their applications, the shape memory alloys with ultra-high performance, such as larger recoverable strain, higher strength, wider temperature range superelasticity, higher response frequency, excellent cycling stability, and larger elastocaloric effect, as well as damping properties, are required. Meanwhile, in order to achieve these goals, the superior performances of shape memory alloys can be tailored by designing the fabricating process, chemical composition and microstructure.

This Special Issue of Metals focuses on relationships between the microstructure and properties of shape memory alloys. The papers presented in this Special Issue provide an account of the fabricating methods, chemical composition, microstructure, martensitic transformation, and mechanical/functional properties of advanced shape memory alloys (see the keywords below). Your contribution is highly valuable and appreciated. We invite you to contribute your research work or review article on the structure and performance of shape memory alloys.

High-entropy shape-memory alloys (HESMAs) exhibit unique properties, including high yield strength, a wide temperature range of phase transformation, and excellent thermal cycling stability, among others. Hence, they have broad prospects for research and application. Currently, various new high-entropy shape-memory alloys have been developed based on TiNi, Fe-based, Ti-based, and NiMn-based alloys. This article focuses on summarizing and analyzing the research status of various types of high-entropy shape-memory alloys, including their microstructure characteristics, martensitic phase transformation, and functional properties. The advantages and disadvantages of high-entropy shape-memory alloys compared to traditional shape-memory alloys are briefly discussed. Finally, based on the analysis of existing problems, future research prospects are proposed, hoping to provide assistance for the development and application of high-entropy shape-memory alloys in the future.
