| 英文摘要 | The effects of hot pressing temperature on microstructures and tensile properties of 15% (volume fraction) SiCp/2000Al composites were investigated in this paper. The relative density of the composites increased rapidly with increasing the hot pressing temperature up to 580 degrees C and decreased with further increasing the temperatures. TEM observations revealed that the interface bonding was quite weak with the interface crack when the hot pressing temperature was below 560 degrees C. When the composites were hot pressed at 580 and 600 degrees C, the interface was clean and had a good interface bonding. The MgAl2O4 and Al4C3 formed at the interfaces when the hot pressing temperature was above 620 degrees C. Tensile tests indicated that the composite fabricated at 580 degrees C exhibited the optimum strength and ductility. Fractography revealed that for the composite fabricated at the hot pressing temperature below 560 degrees C, the fracture mechanism was mainly the interfacial debonding. For the composite fabricated at 580 and 600 degrees C, the fracture mechanism of the composite was the matrix ductile fracture and the SiC particle fracture, When the hot pressing temperature was above 620 degrees C, the interface fractured along MgAl2O4 and Al4C3, and the fracture mechanism of the composite was the matrix ductile fracture, the interface crack and the particle fracture. |
