| 摘 要： | 本文用动态原位法X射线衍射研究了Fe-Ti多层调制膜的固态反应扩散,比较准确地测量了组份调制衍射峰强度的变化,并同时观测了峰位的移动,计算出不同温度下Fe-Ti多层调制膜的扩散系数,并给出其随时间变化的曲线。根据扩散系数随时间变化率,计算出与粘滞弛豫相关的激活能Qy=8.3±0.2kcal/mol。

| Abstract: | Solid state reaction interdiffusion of Fe-Ti multilayer modulated films was investigated by means of dynamic in situ X-ray diffraction. With this method, the measurement of the X-ray modulation peak intensity was relatively accurate and the shift in X-ray modulation peak position was also observed. The interdiffusion coefficients of Fe-Ti modulated films were calculated at different temperatures. Plots of the interdiffusion coefficients versus time at different temperatures were given. According to the variation rate of D vs. τ, the activation enrrgy Qy relative to viscosity relaxation was calculated to be 8.3±0.2 kcal/mol. |
