摘要

The dynamic corrosion behavior of 304 stainless steel in molten Al was investigated at a temperature of 750 °C under varying scouring velocities. The mass loss of the steel at high rotation rates was 5.2 times that of the static condition. A multilayer sandwich structure, comprising “Fe4Al13-Fe2Al5-Fe4Al13”, was formed on the surface of the scoured steel. Within the outer Fe4Al13 sublayer, the original anisotropic grains exhibited gradual growth along the <010> crystallographic direction as the rotation rate increased. The dynamic corrosion process resulted in a significant presence of twins and defects within the intermetallic compound layer, which facilitated the nucleation and growth of the Cr7Al45 phase.
