中文摘要：利用膨胀仪测试了Cu-Al合金在25～700 ℃的热膨胀系数，探讨了淬火处理对Cu-Al合金热膨胀性能的影响。结果表明：淬火处理能改变Cu-Al合金的热膨胀系数，Cu-Al合金淬火处理后的热膨胀系数在290～408 ℃时小于铸态Cu-Al合金的热膨胀系数，其余温度区间均大于铸态Cu-Al合金的热膨胀系数。
英文摘要：The thermal expansion coefficients of Cu-Al alloy at 25～700 ℃ were measured by thermal dilatometer, and the effects of quenching treatment on thermal expansion characteristics of Cu-Al alloy were studied. The results show that quenching treatment can change the thermal expansion coefficients of Cu-Al alloy, and the thermal expansion coefficients of Cu-Al alloy as-quenched is less than that of Cu-Al alloy as-cast at 290～408 ℃, but is larger than that of Cu-Al alloy as- cast at other temperature.
