Abstract: The invention relates to a turbine shaft for a steam turbine, oriented in an axial direction and comprising a first and a second flow region. According to the invention, a first material is provided in the first flow region of the turbine shaft, and a second flow region is provided in the second flow region thereof, the first material having heat-resistant properties and the second material having cold-resistant properties. The inventive turbine shaft is produced by means of a construction weld seam without any previous buffer layer welding on one of the two materials.

Abstract: A turbine shaft, in particular for a steam turbine, is oriented along an axis of rotation. The turbine shaft has a first region with a maximum radius R1 and a second region adjoining the first region and having a maximum radius R2>R1. The first region includes a first base material for use at a temperature of over 550° C. and the second region includes a second base material for use at a temperature below 550° C. An alloy steel used for the first and the second base materials in each case has a chromium content of between 8.0% by weight and 12.5% by weight at a substantially identical austenitizing temperature. A method is provided for producing the turbine shaft.

Abstract: A novel ferritic martensitic alloy is provided. The ferritic martensitic alloy enables the use temperature to be increased from 500° C. to 550° C., where the strength is maintained or is even maximized and the toughness, especially for low temperatures, is maintained compared to the known iron-based alloys. Tunsten is preferably not used.

CPC classification number: C21D9/28

Abstract: The invention relates to a method of introducing compressive residual stresses into shaft notches of a shaft which is configured as a stepped shaft having successive stages having a different diameter. Diameter transitions or notch regions are located between each two adjacent stages. The diameter transitions or notch regions are quenched in a controlled manner as part of a heat treatment of the shaft.
