- 摘要：
- It is conventionally believed that discontinuous precipitation exacerbates alloy corrosion, but its corrosion behavior remains unclear. This work investigates the influence of discontinuous precipitation on the corrosion behavior of a Cu-5.0Ni-1.2Si alloy through microstructural characterization and electrochemical testing. The results demonstrate that fibrous δ-Ni₂Si discontinuous precipitation forms after 4 h of aging at 450°C, occupies approximately half of the microstructure by 8 h, and nearly fully dominates the alloy after 12 h.
