“…Because silver (Ag) does not oxidize and does not react with the superconductor material, it was thought to be a possible substrate for 2G-YBCO conductors. 66,67 However it was found to have some drawbacks such as low melting temperature, high cost of the material, and poor mechanical properties. 68 In addition, it was found to be difficult to maintain the desired texture in Ag.…”

“…The texture can be obtained even in thin ribbons (50 µm) in contrast to pure Ag ribbons where the texture strongly depends on the ribbon thickness and for which no sharp {110} 011 texture was obtained with ribbons thinner than 300 µm. A strong enhancement of the mechanical properties was observed, and the results will be published separately [39].…”

New, mechanically reinforced, {110} textured Ag composite ribbons were fabricated as possible inexpensive substrates for coated conductors without any buffer layer. The key part of this work was the use of a thin but textured Ag outlayer on an AgMg, Ni, or Ni alloys core that ensures the mechanical reinforcement while decreasing the amount of Ag. A thin Cu (50 µm) foil was intercalated between rectangular Ag and AgMg, Ni, or Ni alloys pieces to obtain a tough bond. After sintering, the ingots sustained a cold plastic deformation up to thicknesses of 300, 100 and 50 µm without any intermediate annealing. The prepared composite ribbons were then recrystallized to obtain the {110} texture in the top Ag layer. For the Ag/AgMg ribbons, a further annealing in flowing oxygen was performed to reinforce the ribbons by an internal oxidation process in the AgMg layer without changing the {110} 011 texture in the Ag outerlayer. A unique and stable {110} 011 texture was obtained in Ag/Ni composite ribbons after annealing at 800 • C. The highest degree of texture was observed in 300 µm thick Ag/Ni ribbon, x-ray orientation distribution function and electro backscattered diffraction (EBSD) analysis of the top Ag layer in this ribbon revealed a sharp {110} 011 texture with an in-plane misorientation angle of 10-15 • . Meanwhile, a promising {110} 011 texture was also found in 50 µm thick ribbons with 25 • in-plane misorientation angle. In the last case, a substrate with no more than 16 µm of the textured Ag layer was produced by this new technique, which decreased the total amount of Ag by 40% compared with pure Ag ribbons of the same thickness.
