| Abstract: | The nanometer-level Fe and Cu particulate mixtures were added into Fe-based powder,and the direct carbonizing process in sintering and the carbonzing process after sintering were studied during sintering powder metallurgical parts.The results show that the density, surface hardness and hardened layers of the parts which were directly carbonized are improved compared with carbonizing after sintering. |
| Keywords: | nano-powder sintering carbonization microstructure |
