Refractory Metals › High Temperature Applications

ORNL has processed iridium alloys that are used as primary fuel containment for power generation in all NASA deep space probes, development processing for stable iridium isotopes for use in medical application, and provided assistance in commercial processing of iridium. Additional research areas include tungsten alloy processing for friction stir weld tooling, niobium alloys for use in process equipment for aluminum alloy composites, molybdenum alloys for electrical conversion technology for spacecraft and for space reactor applications, and tungsten electrode materials.
