Cr鑄鐵의 인性 및 耐磨滅性에 關한 硏究

다국어 초록 (Multilingual Abstract)

Toughness and wear resistance of Cr cast iron have been studied at room temperature. Toughness has been investigated by bending test. And Wear resistance teat has been done by high speed wear machine.
The results are as follow;
1. Ms, and Mf temperatures of 12%Cr cast iron ate in the range of 100∼205℃
2. From the result of bending test, it results in lower toughness of 12%Cr cast iron than that of 17% due to lower Cr content.
3. Wear resistance of 12%Cr cast iron is superior to that of 17%Cr cast iron, because it is thought that hardness of 12%Cr cast iron is higher than that of 17%Cr iron to the 4∼5 extent.
4. To improve the wear resistance of cast iron, it is important to control the amout and distribution of K₂carbide in the martrix.
