“…The idea of applying diatomic model to simulate the behavior of amorphous structure was proposed by Guinier [22]. Caron et al [23] once proposed the idea of using XRD analysis to realize the average relative spacing variation with content of alloy elements. In Hufnagel and Brennan's work [24], the model, after some simplifications of mathematical calculation, can be used to evaluate the average atomic distance in the following equation:…”

“…Room-temperature plasticity is one of important requirements for the engineering applications of the BMGs. Majority of Zr-based BMGs are room-temperature brittle although good room-temperature plasticity could be achieved through compositional design [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ], minor addition [ 13 ], cold-rolling [ 14 , 15 ] and sand blasting [ 16 ]. For example, the room-temperature compression plasticity of Zr 70 Ni 16 Cu 6 Al 8 and Zr 70 Al 8 Cu 13.5 Ni 8.5 BMGs can reach up to 40% [ 6 ] and 70% [ 4 ], respectively.…”

A group of plastic Zr-Al-Ni-Cu bulk metallic glasses (BMGs) with low Zr content was developed and their thermal and mechanical properties were investigated. The results show that these Zr-based BMGs have a single crystallization event for all heating rates in the studied temperature region. The glass transition temperature Tg decreases with increasing Zr content for all heating rates. There are two melting procedures for the BMGs whose Zr content is less than 52 at %, while three melting procedures for the other Zr-based BMGs. The second melting procedure is split into two melting procedures for Zr52.5Al12.2Ni12.6Cu22.7 and Zr53Al11.6Ni11.7Cu23.7 BMGs, while the first melting procedure is split into two melting procedures for the other BMGs. The activation energy decreases with increasing sensitivity index β for the studied Zr-based BMGs. The plastic strain εp is in the region of 0.2%–19.1% for these Zr-based BMGs. Both yield strength σy and fracture strength σf are smallest for Zr55Al8.9Ni7.3Cu28.8 BMG whose εp is largest among all studied Zr-based BMGs and reaches up to 19.1%. In addition, the mechanism for the large difference of the plasticity among the studied Zr-based BMGs is also discussed.

“…Even though no quantitative analysis of the average atomic distance was tried, the model for diatomic gas introduced by Guinier [57] was utilized to monitor the alterations in the relative atomic structure of the studied alloys as their chemical composition changed. Hufnagel et al [58], Caron et al [59], Supriya et al [60], Yang et al [61], Sharma et al [62], and Lv et al [63] also applied this model to study the atomic structural changes in BMGs subjected to elastic stress and established a connection between the atomic distance of a diatomic gas molecule and the Bragg diffraction angle, via the following equation:…”

A series of Ti41Zr25Be34-xNix (x = 4, 6, 8, 10 at.%) and Ti41Zr25Be34-xCux (x = 4, 6, 8 at.%) bulk metallic glasses were investigated to examine the influence of Ni and Cu content on the viscosity, thermoplastic formability, and nanoindentation of Ti-based bulk metallic glasses. The results demonstrate that Ti41Zr25Be30Ni4 and Ti41Zr25Be26Cu8 amorphous alloys have superior thermoplastic formability among the Ti41Zr25Be34-xNix and Ti41Zr25Be34-xCux amorphous alloys due to their low viscosity in the supercooled liquid region and wider supercooled liquid region. The hardness and modulus exhibit obvious variations with increasing Ni and Cu content in Ti-based bulk metallic glasses, which can be attributed to alterations in atomic density. Optimal amounts of Ni and Cu in Ti-based bulk metallic glasses enhance thermoplastic formability and mechanical properties. The influence of Ni and Cu content on the hardness of Ti-based bulk metallic glasses is discussed from the perspective of the mean atomic distance.
