Abstract

The effect of solid-state grain growth mechanism on the microstructure evolution was investigated by employing the glass fluxing technique in undercooled Ni-10at.%Fe alloy. The continuous phenomenon of grain size refinement, coarsening and refinement with undercooling (ΔT) was found and corresponded to different mechanism of grain growth after recrystallization: normal growth (ΔT < 70 K) → abnormal growth (70 K < ΔT < 180 K) → normal growth (ΔT > 180 K). Applying the calculation of stress accumulation model after rapid solidification, the influence of ΔT on the driving force of grain growth was analyzed. In combination of the solute trapping model of undercooled melt and solute drag model of solid-state grain growth, the relationship between ΔT and drag force was proposed. Finally, the mechanism of alternant grain growth with ΔT was studied.
