Data-driven discovery of a universal indicator for metallic glass forming ability

Ming-Xing Li et al.

Summary: The glass forming ability of alloys is closely related to the full-width at half-maximum of the first diffraction peak in the X-ray diffraction pattern, providing guidance for the discovery of bulk metallic glasses. Through experimental and computational methods, it has been revealed that the glass forming ability of an alloy is mainly characterized by its amorphous structure. A strong correlation has been found between high glass forming ability and a large dispersion of structural units in the amorphous structure.

Elastic Dipoles in Crystal and Glassy Aluminum and High-Entropy Fe20Ni20Cr20Co20Cu20 Alloy

R. A. Konchakov et al.

Summary: Molecular dynamics simulation reveals the existence of anisotropic local atomic configurations in noncrystalline structures, which resemble interstitial dumbbells in crystals and form a defect subsystem. Based on this, a new approach to identifying defects in model noncrystalline structures has been proposed.

On the Nature of the Excess Internal Energy and Entropy of Metallic Glasses

A. S. Makarov et al.

Summary: The excess internal energy and excess entropy of metallic glasses primarily stem from the elastic energy of the subsystem of interstitial defects, which dissipates into heat under heating and results in complete crystallization.

On the thermodynamics and its connection to structure in the Pt-Pd-Cu-Ni-P bulk metallic glass forming system

Nico Neuber et al.

Summary: Recent studies have shown significant structural differences between Pt-Cu-Ni-P and Pd-Cu-Ni-P metallic glass-forming liquids, with Pd-rich systems exhibiting higher glass-forming ability. An increase in Pd content leads to changes in thermodynamic fragility, showing a stronger behavior.

Dynamic mechanical response of ZrCu-based bulk metallic glasses

K. Tao et al.

Summary: The introduction of Dy element in metallic glasses increases atomic mobility and structural heterogeneity, impacting the dynamic relaxation behavior and mechanical properties. Time-temperature superposition principle, Kohlrausch-Williams-Watts (KWW) function, and quasi-point defects (QPD) theory were used to describe the behavior of metallic glasses. These investigations demonstrate the importance of structure heterogeneity in tailoring the properties of metallic glasses.

One-to-one correlation between the kinetics of the enthalpy changes and the number of defects assumed responsible for structural relaxation in metallic glasses

A. S. Makarov et al.

Summary: This study conducted parallel measurements of enthalpy and high-frequency shear modulus changes during structural relaxation of five bulk metallic glasses. The analysis revealed a one-to-one correlation between the change in molar enthalpy and the alteration in the calculated number of defects based on Interstitialcy theory. The defect formation enthalpy derived from this correlation aligns well with the accepted quantity in the Interstitialcy theory.

Relation of the fragility and heat capacity jump in the supercooled liquid region with the shear modulus relaxation in metallic glasses

A. S. Makarov et al.

Summary: This study focuses on the fragility of supercooled liquids, demonstrating the relationship between fragility and high-frequency shear modulus. The heat capacity jump is also found to be related to fragility and shear modulus relaxation. The results suggest that the evolution of interstitial-type defects frozen-in during glass production mediates the connection between fragility, heat capacity jump, and high-frequency shear modulus in the supercooled liquid state.

Internal friction and dynamic shear modulus of a metallic glass in a seven-orders-of-magnitude frequency range

N. P. Kobelev et al.

Summary: The study reports measurements of internal friction and shear modulus of glassy Cu49Hf42Al9 at different frequencies and temperatures. It is found that the relaxation of internal friction and shear modulus decreases with increasing frequency in the investigated range. A new method for determining the Gibbs activation energy of relaxation is derived, and the underlying activation energy spectrum is found to smoothly increase with accessible activation energies in the experiment.
