- The Behaviour of Misch Metals in Molten Cast Iron
抄録
The effects of the addition of cerium on the macro and microstructure of cast iron have been investigated. <br> The results were as follows. <br> (1) Added on the surface of molten iron, cerium reacts with oxygen so actively that cerium forms oxide and is lost without any suitable flux or coating. <br> (2) The microstructures of cast iron added cerium showed, in turn from surface to bottom, unknown high cerium content ctructure, chilled structure and flake or eutectic graphite structure. <br> The unknown structure consisted of Fe-Ce compound, cerium oxide and cerium sulfide. <br> Cerium was remained in the chilled structure, but in the graphitized structure, cerium could not be detected at all. <br> (3) With the aid of electron probe X-ray micro-analyser, it was cleared that cerium did not exist in cementite but on the boundary between cementite and austenite. <br> (4) Silicon was detected in the same place that had high cerium concentration in the chilled structure.
