We have fabricated GdBa 2 Cu 3 O y (GdBCO) jointed coated conductors (CCs) using a method in which intermediate grown superconductive (iGS) layers of (Y,Gd)Ba 2 Cu 3 O y ((Y,Gd)BCO) are formed from an YBa 2 Cu 3 O y precursor material to investigate their growth mechanism in the superconducting joint. We characterized the nanostructural evolution of the iGS layers by in-plane x-ray diffraction, transmission electron microscopy, and scanning transmission electron microscopy. The iGS layers contained Gd elements and were mainly composed of (Y,Gd)BCO grains. The c -axis oriented (Y,Gd)BCO grains nucleated on the GdBCO layers of both a joining strap and a CC. The thickness of the c -axis oriented (Y,Gd)BCO grains grew with time during the joining process at 800 °C, and finally both of the GdBCO layers were jointed together by the c -axis oriented (Y,Gd)BCO grains, resulting in a wel...

GdBa 2 Cu 3 O y涂层导体之间中间生长的超导接头层的纳米结构演变

我们使用其中（Y，Gd）Ba 2 Cu 3 O y（（Y，Gd）BCO）的中间生长超导（iGS）层的方法制造了GdBa 2 Cu 3 O y（GdBCO）接头涂覆导体（CC）。由YBa 2 Cu 3 O y前驱体材料形成的纳米管，以研究它们在超导接头中的生长机理。我们通过平面X射线衍射，透射电子显微镜和扫描透射电子显微镜表征了iGS层的纳米结构演变。iGS层包含Gd元素，主要由（Y，Gd）BCO晶粒组成。c轴取向（Y，Gd）BCO晶粒在连接带和CC的GdBCO层上成核。在800°C的接合过程中，c轴取向（Y，Gd）BCO晶粒的厚度随时间增长，最后两个GdBCO层都通过c轴取向（Y，Gd）连接在一起
