快速凝固Al-Cu-Si薄带的脆性研究

Embrittlement Research in the Rapid Solidification Al-Cu-Si Ribbons

对用单辊法制备的Al-Cu -Si钎料薄带进行XRD、SEM、DSC分析 ,以及对CuAl2 脆性相进行研究后结果表明 ,CuAl2 相的分布及形态、CuAl2

The Al-Cu-Si brazing ribbon have been prepared by single roller method and analyzed with X-ray diffraction(XRD),scanning electron microscopy(SEM),and differential scanning calorimetry(DSC).It found that the distribution,shape and the metastable structure of the CuAl-2 phase all affect the brazing ribbon brittleness on the study of the CuAl-2 brittle phase.
