Abstract The present work aimed to evaluate the performance of a geometrically optimized stirring apparatus designed for the semisolid state stirring preparation of particle-reinforced aluminum matrix composite, from the perspective of improving particle distribution uniformity. We simulated the flow field of the material system during the semisolid state stirring of B₄C_p/A356 composite by using the FLUENT software while applying the stirring apparatus model with the optimized geometric parameters. We then prepared B₄C_p/A356 aluminum ingots using ordinary stirring apparatus and geometrically optimized stirring apparatus, respectively, and analyzed both macroscopically and microscopically the distribution of B₄C particles in the matrices. The simulation and analysis results showed that the geometrically optimized stirring apparatus can generate an inconstant velocity intersect vortex beneficial to the dispersion of B₄C particles when agitates in the semisolid state aluminum liquid (SSAL). The dual-layer pair-pushing orthogonal paddle with a blade tilt angle of 60° leads to a larger contact area between the blade and the SSAL, and in consequence, contributes to more uniform distribution of B₄C particles in the lower part of aluminum matrix.

Key words： FLUENT B₄C_p/A356 semisolid state stirring method (SSSM) inconstant velocity intersect vortex geometric optimization stirring apparatus
