of A357-SiC nanocomposites. In the first level, a blend of SiC nanoparticles (average size of 50 nm) and pure aluminum powder (average size of 50 μm) were pressed into a disk (diameter of 10 mm) under 15 MPa... random experiments obtained by DX-7 software were performed. By this method, A357-SiC nanocomposites with 0.5, 1.0 and 1.5 wt.% SiC were fabricated at three different frequencies (10, 35 and 60 Hz......
