Abstract: Powder metallurgical method was employed for forming sintered Fe-Cu-C materials from elemental powders. These sintered materials were aimed to be employed as base materials for sintered frictional brake pads. In experimental works, powder mixtures were prepared so that the alloy compositions of Fe-6Cu, Fe-6Cu-1C, Fe-6Cu-2C, Fe-6Cu-3C, Fe-6Cu-4C and Fe-6Cu-5C were obtained. The powder mixtures were processed via a normal ‘press and sinter’ method. The graphite contents of up to 4 wt. % caused increased strengths and hardness but decreased ductility. Increase of graphite contents of up to 3 wt. % tended to reduce friction coefficient of the sintered materials. In contrast, the sintered Fe-6Cu-5C material exhibited low strengths but high friction coefficient. Microstructural observation and phase identification of the sintered Fe-6Cu-5C material indicated the presence of the mixtures of Ledeburite, cementite and pearlite.
