Deformation Behaviour of Semisolid A356 Alloy Slurry between Two Parallel Plates

Abstract:

The deformation of semisolid slurry within a mould or die is complex in the case of semisolid forming. Understanding and improving the efficiency of such a forming process requires a systematic study of the flow of semisolid slurry under deformation. This study considers the flow characteristics of semisolid A356 alloy slurry under deformation between two parallel plates. The semisolid slurry is represented here by an apparent viscosity under deformation and cooling. The process is then modelled using momentum and energy conservation equations, comprising an analytical solution to predict related flow and deformation behaviour of the slurry. The final solution involves coupling the governing equations by developing a numerical code on the FORTRAN platform. The model then predicts the distribution of temperature, solid fraction, apparent viscosity of the semisolid slurry, and stress to deform the slurry. The deformation stress found in this study has a realistic value, which is also supported by the available research. Prediction of deformation characteristics for any semisolid slurry is possible using the present model, which is simple and appropriate. This study also found that the deformation stress increases with an increase in the plate length and decreases with an increase in the slurry deformation velocity.
