Notes:
Warm compacting and sintering behaviors of pre-mixed Fe-2Ni-2Cu-1Mo-1C powderswere studied. Results showed that green density increased with compacting temperature and thenfell slightly; the maximum green density was obtained at about 120°C. Green compact density andspring back effect of the pre-mixed powder increased gradually as the compacting pressureincreased. Sintered density first increased and then fell as the temperatures went up under differentsintering temperatures for 50 minutes, but the trends of sintering dilatation were first reduced andthen increased. Sintered density first reduced and then increased with the prolonged sintering timeat 1300°C, but the trends of dimension change after sintering were the very reverse. Tensile strength,elongation and hardness of the warm compacted Fe-2Ni-2Cu-1Mo-1C materials generally increasedas sintering temperature and sintering time went up
