Claim 0:
1. A method of manufacturing a rotor that defines an axis of rotation for a turbomachine, the method comprising:
providing a lug with a lug body and an interface material disposed on the lug body;
friction welding the lug to a hub member using the interface material, thereby defining a projected structure for an outer radial area of a disc assembly of the rotor;
disposing the projected structure proximate another projected structure that projects from the disc assembly, the projected structure and the other projected structure spaced apart in a circumferential direction relative to the axis of rotation to at least partly define a space for a rotor blade;
removably attaching the rotor blade to the disc assembly within the space; and
the lug body and the hub member made from different materials.
