“…In another work, Fe 26.7 Co 26.7 Ni 26.6 Si 9 B 11 HE-BMG was fabricated and the corresponding studies indicated that the alloy proposes a good bending ductility and superior soft magnetic properties [21]. Wang et al [22] reported that the HE-BMGs are also capable to tolerate the harmful ion irradiation effects and exhibit a favorable response to high levels of helium implantation. Tong et al [23] investigated the effects of aspect ratio on serrated flow dynamic and plasticity of TiZrHfCuNiBe HE-BMG and found that the plasticity and serration size are not monotonic correlated.…”

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.

“…For another, the glass content (mainly including glassy particles and agglutinates) in the lunar regolith generally increases as its maturity (indicates how long a grain has been exposed at the surface) increases, and it is up to ~60 to 70% volume fraction in some highly mature Apollo lunar regolith ( 17 , 18 ), indicating that glass (or glassy state) might be the most suitable and stable material (or structural state) in space environment. It is in line with the experimental results that glassy materials have better irradiation resistance and comparable overall mechanical properties relative to their crystalline counterparts ( 19 ). Meanwhile, glass is also a common component of the regolith for many other planets, such as Mars, Mercury, and Venus, and large asteroids ( 20 ).…”

Physical aging is a long-lasting research hot spot in the glass community, yet its long-term effects remain unclear because of the limited experimental time. In this study, we discover the extraordinary aging effects in five typical lunar glassy particles with diameters ranging from about 20 to 53 micrometers selected from Chang’e-5 lunar regolith. It is found that geological time scales’ aging can lead to unusually huge modulus enhancements larger than 73.5% while much weaker effects on hardness (i.e., varies decoupling evolutions of Young’s modulus and hardness during aging) in these lunar glassy samples. Such extraordinary aging effects are primarily attributed to the natural selected complex glassy compositions and structures, consistent with high entropy and minor element doping criteria, prevailing under the special lunar conditions and the extensive aging time for the lunar glasses. This study offers valuable insights for developing high-performance and stable glassy materials for radiation protection and advanced space explorations.

“…Taking advantage of recent advancement in microstructure characterization technologies, most of the studies mentioned in Table 5 focused on the phase stability and microstructural changes after ion irradiation. Phase stability after irradiation was observed for several HEAs such as CoCrFeNiMn, CoCrFeNiPd and high entropy metallic glasses such as ZrTiHfCuBe and ZrTiHfCuBeNi [340] and Al x CoCrFeNi (x = 0.1-1.5) [82,83]. Such high phase stability was mainly attributed to sluggish diffusion and high configurational entropy that kinetically restrains precipitation by reducing thermodynamic driving force.…”

Alloying has been very common practice in materials engineering to fabricate metals of desirable properties for specific applications. Traditionally, a small amount of the desired material is added to the principal metal. However, a new alloying technique emerged in 2004 with the concept of adding several principal elements in or near equi-atomic concentrations. These are popularly known as high entropy alloys (HEAs) which can have a wide composition range. A vast area of this composition range is still unexplored. The HEAs research community is still trying to identify and characterize the behaviors of these alloys under different scenarios to develop high-performance materials with desired properties and make the next class of advanced materials. Over the years, understanding of the thermodynamics theories, phase stability and manufacturing methods of HEAs has improved. Moreover, HEAs have also shown retention of strength and relevant properties under extreme tribological conditions and radiation. Recent progresses in these fields are surveyed and discussed in this review with a focus on HEAs for use under extreme environments (i.e., wear and irradiation) and their fabrication using additive manufacturing.
