摘要
采用电阻率测试仪研究了加热温度对淬火态Cu-Al合金电阻率的影响。结果表明,在25~380℃范围内,Cu-Al合金的电阻率随着温度的升高而增大;当温度从380℃升至473℃时,合金的电阻率变化不大,而随着温度的进一步升高电阻率再次增大。对上述合金电阻率随加热温度的变化进行了初步分析。
The effect of heating temperature on resistivity of as-quenched Cu-Al alloy was investigated by using resistivity tester.The results show that the resistivity of Cu-Al alloy will increase with the elevation of heating tempera-tures from 25 to 380 ℃;and the resistivity has no appreciable variation at the temperatures ranging from 380 to 473 ℃ and will increase once again with the further elevation of heating temperature.The above-mentioned variation of the resistivity of Cu-Al alloy with heating temperature was preliminarily analyzed.
