This is in good agreement with atomic diameters as estimated by other methods. 它与用其他方法估计出来的原子直径非常符合。
Cu-Al diffusion couples were prepared with mechanical method The Kirkendall effect of atomic diffusion at Cu/ Al interface was investigated by analyzing the changes of the diameters of pin and pinhole respectively during sintering with the help of the OPM and color metallograph. 利用铆钉法制备了Cu-Al扩散偶。借助光学显微镜和彩色金相技术,通过分析烧结过程中销钉及销孔直径尺寸的变化,研究了Cu/Al界面原子扩散的Kirkandall效应。
