- 論文の詳細を見る
The effect of sulfur and oxygen on engulfment and pushing of deoxidation particles of Al2O3 and ZrO2 during solidification of an Fe–10mass%Ni alloy has been studied. The Al2O3 and ZrO2 particles are pushed to the interglobular region where the particle coagulation takes place with an increase in sulfur content. The sulfur contents at the engulfment and pushing transition for ZrO2 and Al2O3 particles are 300 to 400 and about 100 mass ppm, respectively. The ZrO2 and Al2O3 particles are pushed to the interglobular region with an increase in oxygen content. The effect of sulfur and oxygen on engulfment and pushing of particles has been discussed based on the interfacial energy/wetting model and the critical velocity for the engulfment and pushing transition.
