Abstract: A method for making an article from rhenium and in particular a rocket nozzle. First a molybdenum mandrel (10) is formed with a portion having the desired shape of the nozzle. A layer of rhenium (18) is deposited over the nozzle portion (12), and then rhenium wire (20) is wrapped around this rhenium layer (18). A second rhenium layer (22) or a layer of ruthenium is then deposited over the layer of rhenium wire. Alternating layers of rhenium wire and deposited rhenium or ruthenium are applied until a desired thickness is obtained. A layer of molybdenum (26) is applied to can the assembly and the assembly is subject to hot isostatic pressing. Finally, the molybdenum is etched away leaving the rhenium nozzle.
