| Abstract: |
| SiC particle reinforced aluminum matrix composites (SiC/Al composites ) were fabricated by high energy ball milling. The effects of pressure-less sintering temperature between 510℃ and 610℃ on tensile properties of SiC/Al composites was investigated in this paper. The relative density and tensile strength of the composites increased with incresing pressure-less sintering temperature up to 570℃ and exhibited the optimum value, and decreased with further increasing the temperatures.The fracture mechanism of the composites was the matrix ductile frature at the best pressure-less sintering temperature 570℃. And there was no SiC particles at the fracture place. No interfacial reaction between SiC particles and Al matrix occurred during the whole process. |
