运用电位方法测量纯金属铍剩余电阻比,研究了时效处理制度对金属铍的剩余电阻比的影响。结果表明:金属铍的剩余电阻比不仅与时效温度和金属内杂质的浓度有关,而且受时效时间的影响;剩余电阻比值随金属铍样品纯度的增加而增加,纯金属铍(纯度大于99.91%)的剩余电阻比值为20-147,并随时效温度和时效持续时间的不同而变化;高纯度(99.94%)金属铍具有合金时效处理倾向,可以作为时效型微合金来研究杂质对金属的性能影响。
The residual resistance ratio of pure beryllium was measured by potentiometric method. The effect of aging treatment system on the residual resistance ratio of beryllium metal was studied. The results show that the residual resistivity of beryllium is not only related to the aging temperature and the concentration of impurities in the metal, but also affected by the aging time. The ratio of residual resistance increases with the purity of the beryllium sample. Pure beryllium (purity> 99.91% Of the residual resistance ratio of 20-147, and with the aging temperature and aging duration of the different changes; high purity (99.94%) metal beryllium alloy aging tendency, can be used as aging micro-alloy to study the impact of impurities on the performance of metals .
