Abstract
The effects of powder temperature, die temperature, lubricant content and compacting pressure on the behavior of warm compaction of iron based alloy powders at lower temperatures were studied. The optimum die temperature and powder temperature were 120 'C and 100 'C respectively. For Fe-1. 5Cu-0. 5C and Fe-1. 5Ni 0. 5Mo-0. 5Cu-0. 5C powders, the densities of 7. 42 and 7. 41 g/cm3 could be achieved at 686 MPa respectively. For both powders, shrinkage took place during sintering, which was beneficial to further increasing density.
