抄録

The mechanical properties of 0.2∼0.8%C steel castings treated with the iron-calcium base alloy were compared with those of the untreated castings. 24 kg or 3 kg of these steels were melted in a basic high frequency induction furnace, and different amounts of the iron-calcium base alloy were added to them. All heats tested were deoxidized by the same method as described in a previous report(1). The mechanical properties of the cast steels as-cast or annealed and those of the cast steels as-normalized or annealed after forging were investigated.<BR>Results were obtained that the steels treated with the iron-calcium base alloy are characterized by an excellent ductility and a high yield ratio, as a result of cleaner fine grained structures which are caused by the calcium as an effective deoxidizer or degasifier.
