Material Properties of Heat Treated Double Pressed/Sintered P/M Steels in Comparison to Warm Compacted/Sinter Hardened Materials 2003-01-0338
Warm Compaction of Densmix™ powders provides means to produce P/M parts with densities in the range of 7.1 to 7.4 g/cm3. As most properties are improved by increased density, the warm compaction method offers possibilities to increase the competitiveness of P/M compared to other manufacturing techniques.
In this paper a comparison of material properties obtained by two different manufacturing routes is presented. Heat treated properties of some P/M steels after double pressing/sintering are compared with properties obtained with sinterhardening and conventional heat treating of warm compacted Densmix™ powders. Additionally, the single tooth static rupture force and the single tooth bending fatigue strength will be presented.
