摘　　要：采用喷射共沉积方法制备了 6 0 6 1Al/SiCP 金属基复合材料 (MMC) ,研究了 5种热处理制度对其组织和阻尼性能的影响 .结果表明 :不同热处理状态的材料 ,在常温下内耗值基本相同 ,而在高温下则存在显著差别 .在 1 0 0℃～ 2 70℃温度范围内 ,阻尼能力的大小顺序为 :炉冷 >空冷 >-70℃淬火 >原样 >-1 95℃淬火 >水淬 ;在试验温度范围内 ( 30℃～ 4 0 0℃ ) ,模量随温度的升高表现为单调下降 ,随应变振幅的增加而增加 ;同一频率下 。The Influence of five typical heat treatment technologies on the microstructure and damping properties of the 6061 Al/SiC P MMC, which were fabricated by spray-atomization and code-position, is studied. The results show that, damping value changes slightly at low temperature but remarkably at high temperature for the specimens undergoing different heat treatment, between the temperature of 100 ℃and 270 ℃, the damping capacities are ranked from great to small as follow: specimen cooled in furnace, specimen cooled in the air, specimen quenched at -70 ℃, specimen without heat treatment, specimen quenched at -195 ℃ and specimen quenched in water; between the test temperature of 30 ℃ and 400 ℃, the shear modulus decline monotonously as temperature rises and increase with the augment of strain amplitude. Furthermore, the damping capacities don't change with the strain amplitude under the same frequency.
