Analysis of SHPB High Temperature Dynamic Compression Characteristics of 6061 Aluminum Alloy
It is a common way to improve the mechanical properties of aluminum alloy by rolling.The influence of temperature dynamic compression mechanical properties parameters of 6061 aluminum alloy by separating Hopkinson pressure rod loading device(SHPB)was investigated.The results show that the strain signal is first collected by the strain gauge on the incident bar during dynamic compression,and the transmission wave is finally collected by the strain gauge on the transmission bar.When the heating temperature continues to rise,the flow stress decreases,and the decreasing range increases with the increase of the temperature variation amplitude,and the temperature sensitivity is more significant in this process.This study is helpful to improve the mechanical properties of 6061 aluminum alloy and has important metallurgical value.
