Curated summary
This open-access paper studies alloy design and hydrogen embrittlement in corrosion-resistant 60Si2Mn spring rod for high-speed railway service using hydrogen charging, slow-strain-rate tension, permeation, and fracture tests. Cr, Ni, and Cu additions improve the corrosion index, while uniformly dispersed NbC precipitates increase irreversible hydrogen traps and reduce effective hydrogen diffusivity. The findings inform anti-embrittlement material design, but a specific disc spring still requires process and service-environment validation.
