摘要

A method for manufacturing parts for rotary machines, especially turbine wheel disks, having a hub bore in a hub region, as well as turbine wheel disks manufactured by the method, includes pre-turning a contour at the hub region having a profile differing from a hub contour to be produced. At least the hub region is initially treated. At least the hub region having the pre-turned contour is cooled with a coolant fluid after the initial treatment to produce internal compressive strains in the hub region. The pre-turned contour is reduced after the cooling to the hub contour to be produced.
