Zusammenfassung:	The present invention relates to a method of manufacturing a metallic component (1) wherein a plurality of layers of metallic wire (7) is wound around a mandrel or inner layer (2). An outer layer of a metallic material is provided around the wound layers of wire (7) so that a canister (8) is obtained. The canister (8) is then evacuated and sealed before it placed in a hot isostatic pressing device (9) at high pressure and high temperature for a predetermined period of time. Hereby at least a majority of the windings of wire (7) consolidate and diffusion-bond to form the metallic component (1). In some embodiments of the invention, the canister (8) and/or the mandrel/inner layer (2) is/are not removed after the consolidation and thus forms an integral part of the component (1).
