Zusammenfassung:	The invention relates to a process for producing a turbine wheel (10), comprising the following process steps: casting a bar-shaped primary material (3); treating the primary material (3) in a hot isostatic pressing process (HIP process); dividing the HIP-treated primary material (3) into primary shaped parts (4 to 8); forging a blank (9) from each of the primary shaped parts (4 to 8); and creating, in particular milling, a turbine wheel (10) from the blank (9). La présente invention concerne un procédé de production d'une roue de turbine (10), comprenant les étapes suivantes consistant à : couler un matériau primaire en forme de barre (3) ; traiter le matériau primaire (3) dans un procédé de compression isostatique à chaud (procédé HIP) ; diviser le matériau primaire traité dans le procédé HIP (3) en des pièces primaires mises en forme (4 à 8) ; forger une ébauche (9) à partir de chacune des pièces primaires mises en forme (4 à 8) ; et créer, en particulier fraiser, une roue de turbine (10) à partir de l'ébauche (9).
