“…For HESMAs, two or more other alternative elements are introduced to partially replace the initial SMA composition. Therefore, it is essential to select substitute elements that possess good solubility and similar electronic configurations to the primary elements [25][26][27]. Figure 1 displays the equivalent elements for the five principal chemical elements in SMAs, which can promote the development of new types of shape-memory alloys in the future.…”

“…Baiz et al [35] conducted a systematic investigation of the mixing entropy (∆S mix ) and the valence electron concentration (VEC) range of the existing high-entropy shape-memory alloys. It was found that the VEC value should be within the range of 6.8 to 8, and the ∆S mix value should be 1.5R or higher, where R is the gas constant (R = 8.314 J K −1 mol −1 ), [25][26][27] in order to obtain the high-entropy shape-memory alloys. Hence, the values of ∆S mix and VEC should be important considerations in the designing of HESMAs.…”

“…This demonstrates that the NCATB high-entropy shape-memory alloy also has great potential as a high damping material. To expand the temperature range of damping materials, Peltier et al [27] develop a Cu x Fe y Ni z Mn 20 V 11 high-entropy shape-memory alloy. By optimizing the chemical composition, the Cu 11 Fe 29 Ni 29 Mn 20 V 11 high-entropy shape-memory alloy is featured with a single austenitic phase, which possesses the highest plasticity.…”

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.

“…By observing product failure reports, about two-thirds of industrial malfunctions are caused by vibration and noise. The development of materials that integrate high-damping and high-strength functional structures has become a hot research topic [ 5 , 6 ]. Damping alloys are a type of alloy that can meet the needs of high strength and high damping [ 7 ].…”

As the lightest structural metal material, magnesium alloys possess good casting properties, high electrical and thermal conductivity, high electromagnetic shielding, and excellent damping properties. With the increasing demand for lightweight, high-strength, and high-damping structural materials in aviation, automobiles, rail transit, and other industries with serious vibration and noise, damping magnesium alloy materials are becoming one of the important development directions of magnesium alloys. A comprehensive review of the progress in this field is conducive to the development of damping magnesium alloys. This review not only looks back on the traditional damping magnesium alloys represented by Mg-Zr alloys, Mg-Cu-Mn alloys, etc. but also introduces the new damping magnesium materials, such as magnesium matrix composites and porous magnesium. But up to now, there have still been some problems in the research of damping magnesium materials. The effect of spiral dislocation on damping is still unknown and needs to be studied; the contradiction between damping performance and mechanical properties still lacks a good balance method. In the future, the introduction of more diversified damping regulating methods, such as adding other elements and reinforcements, optimizing the manufacturing method of damping magnesium alloy, etc., to solve these issues, will be the development trend of damping magnesium materials.
