| Characteristics of A356/SiCp and A390/SiCp composites
B.-C. Goo, M.-H. Kim
The Journal of Mechanical Science and Technology, vol. 26, no. 7, pp.2097-2100, 2012
Abstract : "Aluminum alloy matrix composites reinforced with SiC particles (AMC) are potential materials applicable to weight reduction of friction
materials. We developed two AMC: A356/SiC and A390/SiC. 30 μm and 60 μm SiC particles with volume fraction of 20% were
dispersed in the matrix of A356 and A390 alloys. When the temperature of the liquid alloy was higher than that of the melting point, SIC
particles floated up to the surface because of the low viscosity, high surface tension and interfacial energy. To mix the ceramic particles,
the aluminum alloy was in the mushy state near the solidus temperature, 610℃ for A356 and 645℃ for A390. Metallurgical, mechanical
and tribological characteristics of the manufactured composites were evaluated."
