摘　　要：利用电导仪测试了高压处理前后LC9铝合金的电导率,探讨了高压处理对LC9铝合金电导率的影响。结果表明:高压处理能降低LC9铝合金的导电率,且电导率随压力的增大略有减小;高压处理后再经时效处理,LC9铝合金的电导率有所升高,压力越大,时效处理后试样的电导率越高。Abstract ：The electrical conductivity of LC9 alloy before and after high pressure treatment was measured by electric conductivity instrument. The effects of high pressure treatment on the electrical conductivity of the alloy were studied. The results show that high pressure treatment can reduce the electrical conductivity of the alloy, and the electrical conductivity can slight decrease with pressure increasing. After high pressure treatment and then aging treatment, the electrical conductivity increases, the electrical conductivity increases with pressure increasing.
