Glass Forming Ability of Zr–(Ni, Cu) Based Ternary Metallic Glasses Based on Bond Parameter Function and Formation Enthalpy Model

Abstract

Zr-based metallic glasses have been extensively studied owing to their high glass forming ability and superior mechanical properties. The glass forming ability of ZrNi(Al, Ti, Nb) and ZrCu(Al, Ti, Fe, Co, Ni) bulk metallic glasses was studied based on the bond parameter function and formation enthalpy model. Elliptical curves can be used to distinguish the glass forming regions from other regions in twodimensional model diagrams. The elliptic parameters can be defined by the relative parameters of the constituent elements. The reproducibilities of this model for ZrNi-and ZrCu-based metallic glasses were 84.4% and 93.4%, respectively, indicating good agreement of this model with available experimental data. The predicted results provide a new strategy for designing excellent-performance metallic glasses.

Interface Characteristics of Tungsten-Particle-Reinforced Zr-Based Bulk-Metallic-Glass Composites with Different Tungsten Particle Sizes

“…Zr-based bulk metallic glass (Zr-BMG) possesses remarkable glass-forming ability and excellent attributes such as high strength, hardness, wear resistance, and corrosion resistance, thereby garnering significant attention. However, its brittleness and lack of macroscopic plasticity greatly limit its practical applications [7][8][9][10]. To enhance the overall performance of Zr-BMG and meet practical requirements, the addition of a second phase to form bulk metallic glass composites with improved plasticity and toughness has been explored.…”
