    摘要: For the grain refinement of aluminum casting alloys, in particular aluminum/silicon casting alloys, gallium phosphide and/or indium phosphide are/is added to the melt, optionally in addition to further grain-refinement and/or modification additions. The addition of gallium phosphide and/or indium phosphide results in a good grain refinement with low shrink-hole tendency and does not have an adverse effect on modification processes.
