Microstructural agent for aluminum alloy castings

摘要

Microstructure having at least one of a heterogeneous nuclear material for refining primary Al and a material for refining eutectic structure, which has a parent phase with the same composition as the cast material to be refined Agent. The microstructure refining agent of the present invention is produced by using a discharge plasma sintering apparatus or the like to produce a mixed powder composed of a parent phase alloy powder, a heterogeneous core material powder, and a flux powder having an element for refining the eutectic structure. Is done.
