2. Relationship between motion of bubbles and agglomeration of inclusions into clusters during solidification of continuously cast steel
Sammanfattning : The possibility of cluster formation during solidication of steel is explored to explain structures that are seen on the fracture surface of the steel. A hypothesis is built that postulates porosities provide favourable locations for inclusions to agglomerate and form clusters. LÄS MER
