Abstract

Determining the component strength from the material strength is an essential but difficult task in dimensioning. Therefore, extensive HCF and VHCF tests are carried out with specimens and thin-walled component-like structures made of X5CrNiCuNb16-4. Despite complex geometry and high-strength material, a local assessment concept of a design code is well applicable. Moreover, specimens and structures show similar VHCF properties, confirming the transferability. Large scatter in lifetime is mainly due to inclusions. Considering the stress intensity factor significantly reduces the scatter and thus enables a more reliable assessment. Furthermore, the area parameter model provides a conservative fatigue strength for 10⁷ cycles.
