Abstract

The method to predict the viscoelastic properties of solidifying alloys is proposed and validated with experiments. The method consists of 2D image-based modeling and finite element analysis.Image-based modeling is based on the water-quenched solidification microstructure. FE analysis simulates uniaxial tensile testing, using the Eulerian-Lagrangian approach in the dynamic explicit procedure. The method enables the derivation of both Young's moduli and rheological properties of Norton's law without semi-solid tensile tests, which are technically demanding and costly, especially in the brittle temperature range. For the Al-5%Mg alloy, the differences between the numerical and experimental properties ranged from 10 to 40%.
