| 摘 要： | 用Ｘ－射线能谱仪测量了７．１～１３．１６ＧＰａ不同压力冲击作用下钨铁耦合体的钨在铁中的扩散浓度。通过研究钨浓度的对数值与扩散深度幂指数的关系，得到了钨动态扩散动力学的类型。找到了一种不用扩散深度计算扩散系数的方法

| Abstract: | Penetration curves of tungsten on iron under 7.1～13.6GPa shocking stress has been studied by means of energy dispersal X-ray spectroscopy (EDAX). Through studying the relation between logarithm of the concentration and power of the penetration distance, the kinetics type of diffusion along dislocation has been found. An attempt was made to determine coefficient without using maximum diffusion depth. The results are right by checking |
