چکیده انگلیسی
Present investigation describes chilled aluminum-quartz particulate composite that can be cast using metallic (copper) chills much like un-reinforced aluminum using conventional aluminum casting equipments. The dispersoid (size distribution 30 to 100 μm) being added ranges from 3 to 12 vol.% in steps of 3%. The resulting composites cast using chills were tested for their mechanical and thermal properties. Microstructures and SEM photographs of fractured and worn surfaces were also taken for analysis. The materials mechanical and thermal properties particularly its improved strength, wear resistance, fracture toughness, hardness, lower coefficient to thermal expansion and thermal conductivity are discussed in some detail.
