摘 要:  研究了Zn含量及残余应变对Cu-8%~13%Zn合金电阻温度曲线的影响。结果表明:CuZn合金电阻温度变量与Zn含量和残余应变无关,在0~150℃温度范围内,Cu8%~13%Zn合金电阻率变量与温度的关系可用ΔρΔt=0.0073×10-6Δt 来计算。讨论了Matthissen定则在高浓度固溶体中的扩展应用。

Abstract: The influence of Zn content and residual strain on the relationship between resistivity and temperature of Cu-8%~13%Zn alloys was studied. The results showed the resistivity variation of studied CuZn alloys due to temperature elevated is independence to Zn content and residual strain. In the range of 0~150℃, the resistivity variation to temperature of studied CuZn alloys follows the relationship of ΔρΔt=0.0073×10-6Δt . And the extended applying of Matthissen rules on high concentration solid solution were farther discussed.
