- 論文の詳細を見る
Unidirectional solidification of hypoeutectic, fully-eutectic and hypereutectic high chromium white cast irons was conducted to clarify their strength and deformation behavior at elevated temperatures. The relation between the microstructure and the high temperature strength was studied at the temperature up to 1073 K. The volume fraction of carbide in the iron depends strongly on its chemical composition. The fully-eutectic iron shows the highest strength within the whole temperature range. The strength reached up to 2800 MPa at room temperature and 500 MPa even at 1073 K. The fully-eutectic iron shows approximately the same hardness and higher compressive strength compared with the hypereutectic iron in spite of a much smaller carbide volume fraction than that of hypereutectic iron. The hypoeutectic iron shows a large amount of plastic deformation, while the fully-eutectic and hypereutectic irons show little plastic strain during deformation due to the presence of brittle carbides. Therefore, the deformation behavior is different in each iron. The rule of mixtures holds for the hypoeutectic and fully-eutectic irons but does not hold for the hypereutectic iron.
