Cube texture evolution of Ni5W alloy substrates and La–Zr–O buffer layer of YBCO-coated conductors
The cube texture evolution of Ni-5 at%W alloy deformed up to a very high strain was thoroughly investigated by X-ray diffraction (XRD) and electron back-scattered diffraction (EBSD) during the process of defor...

Thermophysical properties of solution precursor plasma-sprayed La2Ce2O7 thermal barrier coatings
La2Ce2O7 (LCO) is a promising candidate for thermal barrier coatings (TBCs) due to that it provides better thermal insulation than yttria-stabilized zirconia (YSZ) does. In this work, a TBC LCO was produced by so...

Cube texture formation of Ni9.3W alloy substrates: preparation by optimized deformation sequence and anneal process
The Ni9.3W alloy with no ferromagnetism and high yield strength is one of the most promising textured substrate materials for coated conductors, but its low stacking fault energy makes it difficult to obtain a...
