The design of steam turbine components is driven by high efficiency demands and also requirements for increased operational flexibility due to more renewable energy sources being added to the grid. Therefore, fossil power plants which operate reliabl

The demand for steam turbine components is driven by high efficiency but also by high plant operational flexibility. Steam turbine rotors are therefore exposed to increased temperatures and increased number of stress cycles. These aspects should be c

Fossil fired steam power plants of the latest generation require the elevation of steam parameters pressure and temperature to increase efficiency as well as to reduce greenhouse gas emissions. In order to achieve these goals for high temperatures, n

Large scale specimens with real internal defects were taken from castings. The behaviour of the defects under service like loading conditions (creep, creep–fatigue and fatigue tests at 530°C) was studied, accompanied by non-destructive testing and

To assess creep crack initiation on components, it is necessary to consider the stresses at the crack tip as well as in the remaining ligament or farfield region. For that aim the Two-Criteria-Diagram was established. The method was proven by a large

The applicability of conventional strength hypotheses in the long-term creep range was examined by means of multiaxial loaded small and large-scale specimens of 1% CrMoNiV-steel at 550 o C. The experimentally determined deformation behaviour in the p
