摘要 对Cu Fe爆炸复合薄膜的组织结构进行了光镜、TEM、HRTEM观察。结果表明 :在一定厚度范围内材料纳米晶化 ,有的地方甚至出现非晶相。这是由于在高冲击力、大塑性变形量、高塑变速率以及温度瞬时急剧升降的条件下 ,材料内部位错密度大量增殖缠结 ,空位浓度急剧增加 ,使晶粒碎化成纳米尺度的细晶 ,有的地方原子甚至呈无规则排列。实验结果说明有望采用爆炸冲击制备纳米晶复合薄膜材料。 The structure of Fe/Cu composite film prepared by explosive shock was investigated by metallograph, TEM and HRTEM. The results show that the structure of film has been nano crystallized and even amorphized. Based on the influences of huge shock, high speed heat insulation plastic deformation and instant temperature change resulted from the super conventional condition of explosive shock, many significant changes occurred in the final structure. Besides the great increase in dislocation density and vacancy density, nano crystal and even amorphous structure can also be observed. This result is of significance to manufacture some nanocomposite film with special applications.
