Deformation Behavior of Aluminum Alloys during Solidification

Abstract:

This paper is concerned with the rheological behavior of aluminum alloys during solidification and the modeling aspects of this behavior. The whole range of solid fractions is considered and it is shown that the rheology can be divided into several domains exhibiting quite well-defined characteristics in terms of shear and tensile properties. Modeling based either on suspension approaches for small solid fractions or on porous medium approaches when the crystals mechanically interact is also considered.
