Abstract (en)

[origin: EP1779946A1] An annular metallic article (20) is fabricated by loading a metallic powder (74) into a fill volume (66) of a can (60), compacting the metallic powder (74) by hot isostatic pressing the metallic powder (74) within the can (60) at a temperature above the precipitate solvus temperature and below the solidus temperature of the metallic powder (74) to form a compacted powder mass (76), and ring rolling the compacted powder mass (76) to form the metallic article (20) having the annular circular shape.
