“…Figure 13 shows the shape and surface roughness of the PIM gear of Fe–8 wt % Ni wet-milled powder after debinding and sintering (sintered at 1000 °C for 1 h) [5,21,26]. As clearly seen, the PIM part keeps its fine gear-shape with uniform full density and no distortion.…”

Abstract:This paper provides an overview on our recent investigations on the consolidation of hierarchy-structured nanopowder agglomerates and related applications to net-shaping nanopowder materials. Understanding the nanopowder agglomerate sintering (NAS) process is essential to processing of net-shaped nanopowder materials and components with small and complex shape. The key concept of the NAS process is to enhance material transport through controlling the powder interface volume of nanopowder agglomerates. Based upon this concept, we have suggested a new idea of full density processing for fabricating micro-powder injection molded part using metal nanopowder agglomerates produced by hydrogen reduction of metal oxide powders. Studies on the full density sintering of die compacted-and powder injection molded iron base nano-agglomerate powders are introduced and discussed in terms of densification process and microstructure.
