چکیده
R. Zagórski, S. Golak – Silesian University of Technical, Department of Management and Computer Science, Katowice, Poland The paper deals with computer simulation of gravity casting of the metal matrix composites reinforced with ceramics (MMC) into sand mold . The subject of our int erest is aluminum matrix c omposite (AlMMC) reinforced with c eramic particles i.e. silicon carbide SiC and glass carbon Cg. The created model describes the process taking into account solidifi cation and its infl uence on the distribution of r einforcement particles. The computer calculation has been carried out in 2D system with the use of Navier-Stokes equations using ANSYS FLUENT 13. The Volume of Fluid approach (VOF) and enthalpy method have been used to model the air-fl uid free surface (and also volume fraction of particular continuous phases) and the solidifi cation of the cast, respectively.

ROLE OF SiCp ON THE SOLIDIFICATION RATE AND FORGEABILITY OF STIR CAST LM6/SiCp MMCs
The present paper aims to investigate the solidification behavior and the forgeability of Aluminum alloy (LM6)-SiCp composites at different section of three-stepped composite castings. The temperature of the cast composites during solidification has measured by putting K-type thermocouples at the center of the each step/section, from which the solidification curves were constructed. The forgeab...
