“…In recent years, the experimental results have shown that the strategy for development and fabrication of the high entropy, when employed with care, works efficiently in the design of new BMG materials with excellent properties such as better glass forming ability (GFA) and higher mechanical behaviors compared to the conventional BMGs [10]. Merging inherent traits of BMG and high entropy systems, researchers have recently shown that it is possible to design and produce high entropy alloys with one monolithic amorphous structure [11][12][13]. This combination of materials characteristics has led to the production of novel materials, i.e., high entropy BMG (HE-BMG), with promising functional and mechanical properties [14][15][16][17].…”

This paper aims to show the effects of primary stored energy in high entropy bulk metallic glasses (HE-BMGs) on their relaxation behavior after elastostatic loading process. For this purpose, three HE-BMGs with different chemical compositions and primary stored energy were fabricated. Differential scanning calorimetry and nanoindentation tests were carried out to evaluate the relaxation enthalpy and microscopic mechanical characterization of alloys. The results showed that increase in the number of element types in the alloying composition leads to the increment of stored energy and structural heterogeneity in the primary alloys. Moreover, the elastostatic loading rejuvenates the primary alloys; however, an optimum heterogeneity is needed for the maximum structural heterogeneity and stored energy in the glassy alloy. The hardness measurements also indicate that the elastostatic loading intensifies the hardness variations in the alloys, which may be due to the increased structural heterogeneity.

Rare‐earth‐based high‐entropy alloys (HEAs) with large magnetocaloric effect (MCE) have been recently recognized as good candidates for magnetic refrigeration. Herein, the complex magnetic transition, MCE, refrigerant capacity (RC), and magnetic‐phase diagram of single‐phase TbDyHoEr HEA are studied. It is showed in the results that due to complex magnetic transition and an ideal table‐like MCE, the RC of TbDyHoEr is significantly improved from 883.19 to 1049.22 J kg−1 by melt‐spun treatment. In terms of RC value and hysteresis performance, the melt‐spun treatment significantly improves the application potential of TbDyHoEr HEA as a high‐efficient magnetic refrigeration material, and the ideal table‐like MCE in a large temperature range enables this material to meet the requirements of both cryogenic refrigeration and mesothermal refrigeration for an Ericsson cycle.

“…Up to date, a variety of HEMGs were discovered with their critical size ranging from microto centi-metres [155]. Although the study of HEMGs is still in its infancy, people already discovered some interesting HEMGs, such as the Ti 20 Zr 20 Cu 20 Ni 20 Be 20 HEMG [63] with the critical diameter of 3 mm and its variant (by introducing Hf) with the critical diameter of 15 mm [61], the Sr 20 Ca 20 Yb 20 (Li 0.55 Mg 0.45 ) 20 Zn 20 HEMG with an extremely low T g and elastic modulus that can be imprinted even at room temperature [59], and the Fe 25 Co 25 Ni 25 Mo 5 P 10 B 10 HEMG with a high refrigeration capacity (RC) because of its large magnetic entropy change (∆S M ) [156]. Here, it may be worth noting that, compared to the prototypical magnetocaloric alloy Gd 5 Si 2 Ge 2 with |∆S M | = 18.6 J (kg K) −1 and RC = 305 J kg −1 , the Ho 20 Er 20 Co 20 Al 20 RE 20 (RE = Gd, Dy, and Tm) HEMG reported by Huo et al [157] has |∆S M | = 15.0 J (kg K) −1 and RC = 627 J kg −1 , which is twice of that of Gd 5 Si 2 Ge 2 .…”

Recent development of chemically complex metallic glasses: from accelerated compositional design, additive manufacturing to novel applications

et al. 2022

Metallic glasses or amorphous alloys are an important engineering material that has a history of research of about 80-90 years. While different fast cooling methods were developed for multi-component metallic glasses between 1960s and 1980s, 1990s witnessed a surge of research interest in the development of bulk metallic glasses. Since then, one central theme of research in the metallic-glass community has been compositional design that aims to search for metallic glasses with a better glass forming ability, a larger size and/or more interesting properties, which can hence meet the demands from more important applications. In this review article, we focus on the recent development of chemically complex metallic glasses, such as high entropy metallic glasses, with new tools that were not available or mature yet until recently, such as the state-of-the-art additive manufacturing technologies, high throughput materials design techniques and the methods for big data analyses (e.g. machine learning and artificial intelligence). We also discuss the recent use of metallic glasses in a variety of novel and important applications, from personal healthcare, electric energy transfer to nuclear energy that plays a pivotal role in the battle against global warming.
