Influence of Zn content and residual strain on curve of resistivity vs temperature of Cu-8%～13%Zn alloys

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～ 15 0℃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 .0 0 73× 10 -6 Δt来计算。

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 Δ ρ Δ t =0.007?3×10 -6 ?Δ t . And the extended applying of Matthissen rules on high concentration solid solution were farther discussed.
