| 2 | Effect of alternative magnetic field on the diffusion layer growth in Al/Zn couple显示文摘The influence of an alternative magnetic field on the growth of the diffusion layer in Al-Zn diffusion couple was studied. The thickness of the diffusion layer was examined. The results show that the alternative magnetic field increases the thickness of the diffusion layer and the effect increases with the intensity and frequency of the altemative magnetic field increasing. The growth of the diffusion layer obeys the parabolic rate law and the growth rate increases with the application of the alternative magnetic field. This growth rate change is manifested through a change in the frequency factor k0 and not through a change in the activation energy Q. The frequency factor k0 for the diffusion layer growth with the alternative magnetic field is 5.03 cm2/s and the one without the magnetic field is 3.84 cm2/s. | LIUXiaotao CUIJianzhong WUXiaoming GUOYanhui ZHANGJun | 2004 | Rare Metals2004，23，3： | 0 |
