Multiphase-Field Modeling of Micropore Formation in Metallic Alloys

Michel Rappaz, Alain Jacot, Hossein Meidani

A 3D phase-field (PhF) model has been developed to study the formation of micropores constrained to grow within a well-developed solid network. The model accounts for the equilibrium condition at triple (solid-liquid-pore) lines and the partitioning of dis ...

Phase-field modeling of micropore formation in a solidifying alloy

Hossein Meidani

This thesis is focused on the study of the morphology of micropores formed during solidification of metallic alloys. Micropores constrained to form in well-developed dendritic solid network adopt complex non-spherical shapes. Previous studies using X-ray t ...

3D Phase-Field Simulation of Micropore Formation during Solidification: Morphological Analysis

Michel Rappaz, Alain Jacot, Hossein Meidani

A 3D multiphase-field (PhF) model has been developed in order to study the formation of a micropore constrained to grow in a solid network (i.e., pinching effect). The model accounts for the pressure difference due to capillarity between liquid and gas, th ...

Three-dimensional phase-field simulation of micropore formation during solidification: Morphological analysis and pinching effect

Michel Rappaz, Alain Jacot, Jean-Luc Desbiolles, Hossein Meidani

A three-dimensional (3-D) multiphase-field model has been developed in order to study the formation of a micropore constrained to grow in a solid network (i.e. pinching effect). The model accounts for the pressure difference due to capillarity between liqu ...

Phase-field simulation of micropores constrained by a solid network

Alain Jacot, Milan Felberbaum, Hossein Meidani

A 2D phase-field model has been developed in order to describe the morphology of a pore forming within interdendritic liquid channels and the geometrical effect of mechanical contacts with neighboring solid. The distribution of the solid, liquid and gas ph ...
