Development of metal matrix composite powder cored tubular wire for electron beam freeform fabrication
MetadataShow full item record
Electron Beam Freeform Fabrication (EBF3) is a technique, developed at NASA Langley Research Center (NASA-LaRC), which uses a computerized numerical controlled electron beam welder and a wire feed system to fabricate large scale aerospace parts. Advantages of using EBF3 as opposed to conventional manufacturing methods include decreased deign-to-product time, decreased wasted material, and the ability to adapt controls to produce geometrically complex parts. The EBF3 process is compatible with a range of aerospace alloys and material properties of parts produced by this process have been shown ...
