Titel
Requirements for operational fatigue strength of high quality cast components
Alternative
Hochwertige Gußbauteile. Forderungen zur Betriebsfestigkeit
Abstract
For the fatigue design of high quality cast components the information about service loading, geometry, material behaviour depending on alloy, casting technology, heat treatment and surface state must be available. The influence of these parameters on operational strength is demonstrated on the examples of selected ductile cast iron materials, aluminium alloys and nickel base alloys as well as cast steel. The proof-out of the components must be supported by appropriate quality requirements in design, provision of material and manufacture. However, for safety components, their functionability and fatigue life must be guaranteed by service strain measurements and fatigue tests under variable amplitudes, too.
