Warm Flow Compaction to Form Cross-Shaped Parts with Threaded Holes

Abstract:

The flowability of W-Ni-Fe powders was evaluated through measuring the lateral pressures at different lateral distances in warm flow compacting. Green densities at different lateral distances were also tested. In addition, cross-shaped parts with threaded holes were trial produced. The results showed that, at lateral distance of 2 mm, the lateral pressure was 101.9 MPa and the green density was 9.09 g·cm^-3 when compacted under 600 MPa at 96°C. Warm flow compaction could form cross-shaped parts with lengthwise and lateral threaded holes.
