| 1. | In this paper , 6013al / sicp / gr metal matrix composite ( mmc ) was produced by spray codeposition , by means of changing the medium of quenching , influence of five types of heat treatment system ( furnace cooling , air cooling , water quenching , dry ice quenching , liquid nitrogen quenching ) and different aging temperature on the damping was studied systematically 本文采用喷射共沉积方法制备了6013al sicp gr金属基复合材料( mmc ) ,通过改变淬火介质,较为系统地研究了五种热处理制度(炉冷、空冷、水冷、干冰冷及液氮冷)以及不同时效温度( 120 、 150 、 170 、 190及210 )对6013al sicp grmmc阻尼性能影响。 |
