Abstract

On the basis of the novel binary CuZr bulk metallic glass (BMG), we report the excellent glass-forming ability (GFA) in the simple Cu₅₀Zr₅₀-based BMG-forming alloys with minor Al addition. When Al addition changes from 4 to 8 at.%, Cu₅₀Zr₅₀-based BMGs can be produced to cylindrical rods with a diameter of at least 5 mm. The alloys have a broad glass-forming composition range with the excellent GFA. The elastic moduli were derived from the ultrasonic and density measurements. The physical origin of this unique GFA in the alloys is investigated. Our results might provide an effective route for exploring new BMGs.

Assessment of the classical theory validity through Cu<inf>50</inf>Zr<inf>50</inf> nucleation and growth molecular dynamics simulations
2024, Journal of Non-Crystalline Solids
One of the most promising candidates for novel glass-forming alloy design is atomic-scale simulations, primarily due to their capability to compute properties that are usually experimentally difficult to measure. This work aims to use classical molecular dynamics (MD) simulations to obtain the key nucleation and growth variables for the glass-forming Cu₅₀Zr₅₀ alloy while verifying the validity of the Classical Nucleation Theory (CNT). Through CNT equations and simulation data, nucleation and growth rates could be determined, revealing good agreement between CNT expressions and simulation results. The data were compared with other simulation and experimental data, providing reasonable evidence that supports the validity of CNT for describing the solidification behavior of glassy alloys. Simulation data seems to overestimate the experimental growth rate by one order of magnitude, a trend that requires further investigation and correlation with the system/potential to enhance the method’s robustness and reliability for other alloy compositions.
Crystallization kinetics and nanoindentation studies of Cu<inf>46</inf>Zr<inf>40</inf>Ti<inf>8.5</inf>Al<inf>5.5</inf> glassy alloy
2024, Journal of Non-Crystalline Solids
Crystallization kinetics of Cu₄₆Zr₄₀Ti_8.5Al_5.5 metallic glass is investigated in non-isothermal and isothermal conditions. In non-isothermal condition, the crystallization activation energy is determined using Kissinger's method. Further, activation energy of reported Cu-Zr-Al metallic glasses are compared with Cu₄₆Zr₄₀Ti_8.5Al_5.5 alloy to understand the effect of Ti addition on crystallization kinetics. Detailed investigation on activation energy through the crystallization process is studied. To understand the influence of nucleation and growth mechanism during the crystallization steps, samples are heated in isothermal conditions at various annealing temperatures in supercooled liquid region to determine the local Avrami's exponent using Johnson-Mehl-Avrami equation. Additionally, small scale mechanical response is noted on metallic glass sample to determine the influence of structure on hardness and elastic modulus. Nanoindentation results showed hardness value of 5.39 ± 0.09 GPa and Young's modulus of 92.81± 0.52 GPa.
A novel criterion for predicting the glass-forming ability in Zr–Cu–Al ternary alloys: A molecular dynamics study
2024, Intermetallics
The molecular dynamics simulation is used to investigate the correlation between the atomic scale structure and glass-forming ability (GFA) of the ternary (Zr_0.5Cu_0.5)_100-xAl_x (x = 2, 4, 6, 8, 10, 12) bulk metallic glasses. Different techniques, like the Voronoi tessellation, are exploited to quantify this system's topological and chemical short-range ordering. It is found that the potential energy and the virial stress energy density of the icosahedra reveal the geometrical and chemical ordering in this system, respectively. Accordingly, a new GFA prediction criterion is presented, and the criterion's feasibility is demonstrated for various compositions by comparing the predicted and experimental data. It is found that Zr₄₆Cu₄₆Al₈, Zr₇₀Cu₂₀Al₁₀, and Zr₄₀Cu₁₀Al₅₀ alloys are the optimal compounds with respect to GFA.
Thermal stability and crystallisation behavior of newly developed Cu–Zr–Ag–Ti–Ni multicomponent bulk metallic glass
2023, Materials Chemistry and Physics
A comprehensive understanding of the thermal stability of multicomponent bulk metallic glasses (MBMGs) is imperative for their possible technological applications. In this study, new MBMGs, Cu₃₉Zr₄₂Ag₉Ti₁₀ and Cu₃₂Zr₃₉Ag₈Ti₉Ni₁₂, were developed employing a multilayer perceptron neural network, intelligently expanding the binary Cu₅₀Zr₅₀ BMG. X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses were used to confirm the amorphous nature of the as-cast alloys. The crystallisation kinetics of the alloys were investigated using differential scanning calorimetry (DSC) under isochronal conditions at different heating rates coupled with microstructural analyses tools. The thermal attributes suggest that glass transition and crystallisation are more sluggish in the case of Cu₃₂Zr₃₉Ag₈Ti₉Ni₁₂ compared to Cu₃₉Zr₄₂Ag₉Ti₁₀. The local activation energies ( $E_{α}$ ) and the Avrami exponent ( $n_{α}$ ) indicate a diffusion-controlled crystallisation mechanism for both alloys. The nucleation rate of the crystalline phase(s) is relatively lower for Cu₃₂Zr₃₉Ag₈Ti₉Ni₁₂, indicating sluggish crystallisation. Moreover, the rate of change of $n_{α}$ becomes much slower for Cu₃₂Zr₃₉Ag₈Ti₉Ni₁₂ MBMG during the later stages of crystallisation owing to higher undercooling and, thus, a higher required driving force for the growth of nucleated phases. The free volume of Cu₃₂Zr₃₉Ag₈Ti₉Ni₁₂ remains smaller at both room and elevated temperatures, pointing towards its better glass forming ability. XRD and TEM analyses of the crystallised alloys suggested progressively increasing precipitation of the topologically disordered Cu₁₀Zr₇ phase from Cu₄₂Zr₄₈Ag₁₀ to Cu₃₂Zr₃₉Ag₈Ti₉Ni₁₂ MBMG, potentially aiding in its increased thermal stability.
Influence of sulfur addition on the glass formation, phase transformation and mechanical properties of Cu<inf>50</inf>Zr<inf>50</inf> alloy
2023, Acta Materialia
In this work, a thorough study on the effects of sulfur-addition in the Cu₅₀Zr₅₀ glass-forming system was conducted using laboratory-based X-ray diffraction (XRD), synchrotron-based high-energy XRD (HESXRD), differential scanning calorimetry, and uniaxial compression testing. We report that the glass-forming ability (GFA), thermal stability, phase transformation sequence during heating and cooling, as well as the mechanical properties of the Cu₅₀Zr₅₀ system are highly sensitive to the sulfur concentration. Proper addition of sulfur can not only stabilize the B2-CuZr phase, but also enhances the GFA of the system. This enables the formation of BMG composites that solely contain a B2 phase, which results in a combination of high strength and substantial plastic strain under compressive loading. The total strains of the newly developed BMG composites with sulfur contents of 0.5 and 1.0 at.% are as large as ∼10 at.%, exceeding the previously reported strains of the Cu₅₀Zr₅₀ BMG by far. These superior properties make the Cu-Zr-S BMG composites a promising candidate material for industrial applications. In addition, it is found that excessive addition of sulfur leads to the precipitation of the Cu₁₀Zr₇ phase upon cooling from the alloy melt and a sulfide phase during heating from the glassy state. HESXRD experiments suggest that the preferential bonding between Zr and S atoms could be the determining structural mechanism on the atomic scale, leading to the changing primary crystallization sequence for heating and cooling. The findings in this work further strengthen the high relevance of sulfur in alloy development and tuning of properties in BMGs, especially considering the low cost, good availability, and non-toxicity of sulfur in the relevant modifications.
Role of Al in Cu-Zr-Al thin film metallic glasses: Molecular dynamics and experimental study
2023, Computational Materials Science
The paper deals with the role of Al in thin film metallic glasses based on Cu and Zr. We employ a combination of molecular-dynamics simulations of the atom-by-atom growth process with magnetron sputtering. We use the previously studied composition Cu_0.46Zr_0.54 as a starting point, and focus on the effect of Al incorporation into Cu_0.46Zr_0.54 (simulations) and Cu_0.46(Zr + Hf)_0.54 (sputtering). We go beyond the state-of-the-art by quantifying the homogeneity, densification, short-range order (bonding preferences and coordination numbers), medium-range order (common neighbor and network ring statistics) and functional properties (hardness, Young's modulus, glass transition temperature and crystallization temperature) in a wide range of Al contents (0 to 20 at.%) and growth conditions. We identify the key building blocks of Cu-Zr-Al: icosahedral clusters (12 vertices) centered around Cu and Al, and supraicosahedral clusters (16 vertices) centered around Zr. The atomic-scale simulations provide a lot of information not accessible experimentally and explain the experimental data. The results are important for understanding the structures and properties of this class of metallic glasses, and for optimizing their compositions and pathways for their preparation for various technological applications.
