Recent advancements in powder modification and manufacturing techniques have lead to significantly enhanced production properties for molybdenum-rhenium (Mo-Re) components. This enhancement is the result of improved processing developments for the manufacturing of composite Mo-Re powders. A direct benefit of using this type of powder is a decrease in the requirements for segregation-control, and related processing equipment Generally, traditional techniques for Mo-Re compaction involve powder blending, pressing, pre-sintering and sintering, but the use of composite Mo-Re powders allows the two-step sintering method to be replaced by a lower temperature, one-step operation. The compacts formed from the composite powder using this method approach full density at only two-thirds the temperature required for traditional powder applications. This measurable decrease in temperature requirements and a decrease in the need for segregation-control provide a reduction in processing-cost, while simultaneously increasing processing options.
