| Abstract: | Microstructures and properties of two iron-base sintered materials, both with and without forging were comparatively studied. The results show that the mechanical properties of the forged (materials) are far better than the sintered ones. The microstructures of the forged (materials) are close to compact structures; their density reached 7.60~7.70 g/cm~3; their apparent hardness HRB increased by about 50%; and their tribological characteristics remarkably improved. |
