Relationships between the reinforcement properties and the crystallization of MMc

Occurrence of a reinforcing phase in a cooling composite casting causes that its crystallization goes differently as compared to the casting without reinforcing (of traditional design). This affects the forming process of the composite structure since the moment of mixing of the components until total solidification of the composite matrix. The present paper aims at presenting several problems related to crystallization of composite castings (particle reinforced and with saturated reinforcement) that have been the subjects of the research work performed by the team of the Foundry Section of the Poznan University of Technology. The review displays the spheres of the technology of composite casting materials that are well known and the ones that require more detailed research.
