By comparing the quenching performance and microstructure characteristics of the two aluminum alloys, the difference and reasons of their quench sensitivity are analyzed. In this study, SEM, TEM, EDS and other methods were used to observe and analyze 6082 and 6061 aluminum alloys under different quenching conditions. Meanwhile, thermal couple and metallographic observation method were used to test the temperature and microstructure changes before and after heat treatment. The results show that 6082 aluminum alloy exhibits significant quenching sensitivity during quenching process, while 6061 aluminum alloy shows relatively stable performance. By comparing the microstructure characteristics of the two aluminum alloys, it is found that the increased nitrogen content and high silicon content of 6082 aluminum alloy have led to its enhanced quench sensitivity.【Keywords】精品文档---下载后可任意编辑6082 aluminum alloy; 6061 aluminum alloy; quench sensitivity; microstructure characteristics; nitrogen content; silicon content
