Claim 5:
6. A method for manufacturing an integrally formed bladed disk of a turbomachine, said method comprising:
manufacturing a plurality of blades, the blades comprising a root and a profiled portion;
placing the blades in an annular spark plasma sintering mold which comprises a first metal powder and a second metal powder, the blades being angularly distributed over a contour of the annular spark plasma sintering mold, the profiled portion of the blades protruding from the first and second metal powders radially outwardly, the root of the blades being embedded into the first metal powder so that the first metal powder forms an outer portion of a central hub of the bladed disk to be manufactured, the second metal powder being surrounded by the first metal powder so that the second metal powder forms an inner portion of the central hub of the bladed disk to be manufactured;
spark plasma sintering the blades with the first metal powder and the second metal powder,
the blades being monocrystalline before and after the spark plasma sintering.
