Abstract

See full text

A method is described for the production of bulk rapidly solidified metallic articles of near-net shape, by depositing multiple thin layers of feedstock using an energy beam to fuse each layer onto a substrate. The feedstock may be in the form of metal powder or wire. Different finished geometries are also described.
