| 中文摘要 | The orientation relationship (OR) and the interfacial structure between Nb solid solution (Nbss) precipitates and alpha-Nb(5)Si(3) intermetallics have been investigated by transmission electron microscopy (TEM). The OR between Nbss and alpha-Nb(5)Si(3) was determined by selected-area electron diffraction analyses as (222)(Nb)//(002)(alpha) and [1 (1) over bar0](Nb)//[1 (1) over bar0](alpha) High-resolution TEM images of the Nbss/a-Nb5Si3 interface were presented. Steps existed at the interface that acted as centers of stress concentration and released the distortion of lattices to decrease the interfacial energy. In addition, the interfacial models were proposed based on the observed OR to describe the atomic matching of the interface. The distribution of alloying elements at the Nbss/alpha-Nb(5)Si(3) interface has also been investigated, and Hf was enriched at the interface to strengthen the grain boundary. |
