摘要: There are many approaches to fabricate nanoparticles reinforced aluminum matrix composites. However, uniform distribution of nanoparticle within remains a difficult challenge. In this study, novel method is used by taking the advantages from squeeze casting semi-solid slurry combined with electromagnetic field refine microstructure primary Al and eutectic Si phase, plus obtain nano alumina particles in matrix. It noted that plays an important role formation non-dendritic α-Al great refinement occurs as consequence pressure application. can be seen increase causes smaller rounder particles. A comparative study on abrasive wear behavior Al2O3 metal composite has been carried out present investigation. The mass loss pin was effect addition resistance materials.
