• 論文の詳細を見る

• Remarkable segregation was observed in the modified super clean CrMoV steel forgings for electric power generation applications. Therefore, in order to make clear the mechanism, effect of such elements as Mn, Ni, Cr and Mo on segregation was studied, using 8 tons sand mold ingots and unidirectionally solidified experimental ingots. As the result, it has been found that remarkable macrosegregation with opposite inclining angle compared with that seen in conventional ingots was formed by the sinking of heavy segregated liquid. It has also found that remarkable carbon segregation was formed because of small partition coefficient of carbon due to high δ solidification ratio and because of heavy density due to high Mo content.
