Abstract:

Several recent developments in powder metallurgy PM rhenium have significantly enhanced the uses and usability of rhenium and rhenium alloys. One of the developments was cold isostatic pressing CIP to a complex shape with traditional rhenium powder. CIPing to a complex shape with a one or two-part mandrel reduces the quantity of rhenium required to produce the component and significantly reduces the secondary machining. The CIP-to-complex shape method was developed for rhenium liquid-fueled apogee engine combustion chambers. The other major development was high-density spherical rhenium powder SReP, which has excellent flow for use in traditional and advanced processes for PM rhenium. Several advanced consolidation techniques were investigated vacuum plasma spraying VPS direct hot isostatic D-HIP and laser additive manufacturing LAM to produce near net shape components. All of the recent developments will lower the cost, reduce the processing time, and improve the yields when making powder metallurgy rhenium and rhenium alloy components.
