二元Cu合金的光反射率与光阻尼系数

REFLECTANCE AND DAMPER COEFFICIENT OF BINARY COPPER ALLOYS

研究了二元 Cu 合金光反射率 R 与光波长λ的关系以及 Al,Zn,Mo,Si,Ni,稀土元素、大气停留时间和腐蚀作用的影响。研究表明,在本实验情况下,二元 Cu 合金的 R-λ关系为:R=a-bλ^(-1/2)估算了光在二元 Cu 合金中传播的阻尼系数、固溶在 Cu 中的过渡族金属的价电子数.

The relationship between reflectance(R)and wavelength(λ)isone of the base data for calculating chromaticity of alloys.The reflectance ofbinary copper alloys and effect of alloying elements Al,Zn,Mn,Si,Ni,RE,aging time and etching on the reflectance has been studied.The resultsshow that the reflectance of copper alloys can be given by an equation of theformR=a-bλ^(-1/2)The damper coefficient of copper alloys containing Al,Ni,Mn,or Zn hasbeen calculated according to the electromagnetic theory and the number of val-ence electron of transition metals Mn and Ni in copper alloy has been evaluat-ed.It shows that damper coefficient of copper alloys increases as the alloyingelements increase.
