Abstract

The current research has resulted in the development of a new AA7178/SiC nanocomposite. The bottom pouring stir casting process was used to manufacture the composite material that has 1, 2 and 3% (weight) SiC reinforcement nanoparticles in it. Microstructural research showed that the matrix and reinforcement phases did not react with each other while the material was being processed. As a result, a strong bonding was achieved that was devoid of porosity and agglomeration. An electron backscatter diffraction (EBSD) investigation indicated the formation of finer grains from coarser grains.
