| Abstract: | The Fe-2Mn-2Cu-Mo-C-P powder is prepared by means of high-energy ball-milling method. The variation forms of powder and the effect of ball-milling time on green density and sintered density are studied. The result shows that after 8 hours of ball-milling the compacted and sintered powders own 7. 21 g/ cm^3 of material density and 230-240 Hv5 value after annealing. The material is characterized by a good thermoplastic and hardness. It is suitable for producing synchronizer ring by hot powder forging. |
