## Description

- description: Nb3Sn remains an indispensable material for high-field applications,
    including fusion reactors, particle accelerators, and nuclear magnetic resonance
    systems, owing to its excellent manufacturability and high-field performance.
    Despite more than 70 years of research, its phase-formation mechanism has not
    yet been fully elucidated, leaving considerable scope for further performance
    improvement. This review summarizes recent advances in Nb3Sn conductor development
    from the perspectives of thermodynamics, diffusion kinetics, and elemental-addition
    strategies, with particular emphasis on phase formation during diffusion reactions.
    Key topics include control of the Sn chemical potential, diffusion behavior of
    Sn and Cu, Ti and Zn addition effects, grain-boundary chemistry, multielement
    addition strategies, and strengthening of the Sn core. The review provides a unified
    thermodynamic and kinetic framework for understanding and optimizing Nb3Sn layer
    formation.
