Abstract
Tensile and fatigue tests of two compositions of steels, Fe-0.6%C-l.7%Cu and Fe-0.8%C-2.1 %Cu sintered at wide range of temperatures from 900°C to 1200°C were carried out to investigate effects of element content and sintering temperature. When the sintering temperature was higher than 1100°C, Fe-0.8%C-2.1%Cu steel exhibited higher density, tensile strength, elongation and fatigue strength compared to the other steel. The higher Cu content results in the higher density because Cu contributes to liquid phase in the sintering process. The higher C content contributes to the higher tensile strength, elongation and fatigue strength due to formation of pearlite phase. When the sintering temperature was lower than 1000°C, density, tensile strength and elongation were low. However, the metal copper phase still remains after sintering.
