FeNi binary metallic glass exhibits excellent mechanical properties, soft magnetic performance and corrosion resistance, endowing it with broad application prospects in aerospace, electronic information, precision manufacturing, energy industry and other fields. In this work, molecular dynamics simulation is adopted to investigate Fe50Ni50 binary metallic glass. By applying pulsed current, the regulation mechanism of pulsed current voltage on the microstructure and mechanical properties of the material is systematically explored. The results reveal that pulsed current can significantly optimize the mechanical properties of the system. With the increase of voltage, the yield strength of the material gradually rises, the yield strain is expanded, the stress attenuation in the plastic stage is greatly reduced, the residual stress is maintained at a higher level, and the structural stability is substantially improved. Accordingly, the regulation effect of electric field on mechanical properties provides a solid theoretical foundation for the performance optimization of FeNi metallic glass.
