Cooling-Rate Dependent Structural Evolution and Glass Formation in Cu₅₀Ti₄₂Ni₈ Alloy: A Molecular Dynamics Study
Subject area: Science,Engineering and Technology · Area of research: Physics

Abstract
Molecular dynamics (MD) simulation based on the Embedded Atom Method (EAM) potential was used to study the structural evolution and glass forming ability of the ternary Cu50Ti42Ni8 alloy. The alloy system was melted and quickly cooled down to give an amorphous structure. The radial distribution functions were used to study the structural evolution during solidification, showing the changes in the atomic packing and short-range order. Incorporation of Ni contributes to the generation of stable Cu–Ti–Ni atomic clusters, thereby enhancing the structural stability and mechanical performance of the alloy. Glass transition temperature and crystallization resistance, thermal properties, indicate the enhanced glass-forming ability which is attributed to the increased thermal stability and suppressed crystallization
