Abstract:

The objective of this study is to investigate the feasibility of injection molding tungsten heavy alloys into net or near-net shape parts. The focus was to demonstrate that powder injection molding can provide parts with equivalent or superior sintered material properties to those that have been achieved for presssintering heavy alloys of similar compositions. In addition, geometric shrinkage and key process variables were identified and analyzed. This investigation was divided into twelve tasks including elemental particle analysis using laser diffraction powder blending solid loading curve feedstock rheology feedstock mixing prototype test mold injection molding furnacing thermal debinding and sintering and mechanical properties.
