Aluminium composites casting in rotating magnetic field

In this paper technological and material conception of composite manufacturing with intensify of ex-situ powders and some results was shown. Technology of powders stirring with liquid metal in the crucible was shown. For composites required dispersion of reinforcement and matrix crystallization was assisted with rotating electromagnetic field. Improvement of reinforcing particles distribution can be observed. Composite structure was studied with use of light microscopy. Electromagnetic field processing positive influence on reinforcing phase distribution and matrix crystallization process was proved.
