| 摘 要： | 采用微波烧结的方法，在烧结温度分别为680℃，710℃，740℃，770℃，800℃制备了15％的SiCp／Al复合材料。探讨温度对材料的致密度和力学性能的影响。结果表明：致密度和材料硬度及冲击韧性随温度变化呈马鞍形，在770℃样品的密度和硬度及冲击韧性达到最佳值，分别为2．62g／cm3，42．6MPa，40J／cm2。结论：用微波烧结SiCp／Al复合材料可在短时间内使样品达到烧结致密化，缩短烧结时间，节约能源。

| Abstract: | Using microwave sintering , the SiCp/A1 composite materials which SiC content was 15wt% were prepared in the sintering temperature 680 ℃, 710 ℃, 740 ℃, 770 ℃, 800℃ respectively. The influence of temperature on the densification and mechanical properties of composites was studied. The results showed that： the density, hardness and impact toughness of composites were changing with sintering temperature changing. When the sintering temperature was 770℃, the density and hardness and impact toughness to achieve the best value, which were 2.62 g/cm3, 42.6 MPa, 40 J/cm2 respectively. Conclusion. The microwave sintering can prepare densified SiCp/Al composite in a short time thus shorten the sintering time and saved energy. |
