| Abstract |
Liquid phase sintering of cast iron powder compacts added 0-5% Cu, or the same contents Cu and 0.4% phosphor, at 1100℃ or 1120℃ in H_2 atmosphere was studied. In the case of copper addition, the maximum sintered density of 6.3g/㎤ and the maximum tensile strength of 300㎫ were obtained at 2% copper. On the contrary, in the case of both copper and phosphor addition, the sintered density decreased with increasing copper content because of compacts swelling in pressing direction. This phenomenon might be due to the bad wettability of P-containing liquid phase on the surface of cast iron powder. |
