“Direct” P/M Processing Concepts
Press and Sinter Process
- Potentially low cost, net shape process
- Liquid state sintering to bond powder particles
- Typically 95-97% final part density
Direct Powder Forging Process
- Use of forging to mechanically consolidate powder preforms
- Improved density and properties compared to press and sinter products
Potential Benefits
- Can incorporate more reactive reinforcements without substantial degradation
