Traditional techniques for Mo-Re compaction involve powder blending, pressing, pre-sintering, and sintering, but composite Mo-Re powders allow the two-step sintering method to be replaced by a lower-temperature, one-step operation. The composite powder reduces segregation and increases homogeneity. In addition, the compacts formed from the composite powder approach full density at only two-thirds the temperature required for traditional powder compaction. This measurable decrease in temperature requirements and a decrease in the need for segregation control together enable reduced processing costs, while simultaneously in-creasing processing options. This paper is the result of a study comparing Mo-Re composite powder with traditionally blended Mo-Re powder. The study compared powder characteristics and morphologies along with various physical and mechanical properties of the respective compacts.
