Prediction of local properties

The design of safety-relevant castings in lightweight constructions requires consideration of the inhomogeneous material properties already in the design phase. Usually global component properties are used for the dimensioning of constructions, for example the volume fraction of the porosity with regard to the vibration resistance. It is striven for to differentiate the influence of microstructure and casting defects on mechanical properties depending on type, size, morphology and location of the defects. The results, fed into lifetime calculation and coupled with process simulation, should allow an early assessment of manufacturing-related errors to derive constructive improvements.
