“…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]. For instance, Wang et al [18] showed that the thermoplastic formability of TiZrHfNiCuBe alloy strongly depends on Newtonian flow and it can be improved by vibrational loading.…”

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.

“…There are several works focusing on the study of inherent features of HEBMGs. [11][12][13][14][15] Duan et al [16] indicated that the shear modulus relaxation data could be employed to evaluate the effects of structural relaxation, glass transition, and crystallization in TiZrHfCuNiBe alloy. Gu et al [17] found that the relaxation enthalpy monotonically enhanced with the application of cryogenic cycling treatment.…”

The role of the microalloying process in relaxation behavior and crystallization evolution of Zr20Cu20Ni20Ti20Hf20 high entropy bulk metallic glass (HEBMG) was investigated. We selected Al and Nb elements as minor elements, which led to the negative and positive effects on the heat of mixing in the master HEBMG composition, respectively. According to the results, both elements intensified β relaxation in the structure; however, α relaxation remained stable. By using different frequencies in dynamic mechanical analysis, it was revealed that the activation energy of β relaxation for the Nb-added sample was much higher, which was due to the creation of significant structural heterogeneity under the microalloying process. Moreover, it was found that Nb addition led to a diversity in crystallization stages at the supercooled liquid region. It was suggested that the severe structural heterogeneity in the Nb-added sample provided multiple energy-level sites in the structure for enhancing the crystallization stages.

“…Amorphous HEAs show various applications in industry, due to their unique physical and chemical properties. [84] Amorphous HEAs can be fabricated with a low critical cooling rate even down to 10 K•s −1 . On the other hand, amorphization can be observed in FCC HEAs subjected to high-pressure torsion.…”
