摘要 ：
MgB 2 superconductor bulks were fabricated using Mg and B precursors. The physical state of Mg (solid, liquid, or gas) significantly influences the final product, MgB 2 bulk. In this study, the Solid -Solid, Liquid-Solid, and GasSolid methods were employed to fabricate MgB 2 bulks. The superconducting properties and microstructure of various samples were systematically investigated. Notably, for the first time, nano -CT was utilized to comprehensively and non-destructively analyze the microstructure of MgB 2 bulks, particularly the size and distribution of voids, which serve as the primary barrier affecting the superconducting properties. By examining the microstructure characteristics, the infiltration effect of Mg in different physical states during the reaction was analyzed, and a feasible reaction model was established. This research contributes to a better understanding of the reaction mechanism of MgB 2 , which may aid other researchers in enhancing the properties of MgB 2 superconductors.

摘要 ：
The Ni-5 at.%W/Ni-9.3 at.%W/Ni-5 at.%W alloy composite substrate with a thickness of 109 mu m was produced by powder metallurgy and rolling process. The composite substrates with different thicknesses were produced by electrochemically polishing the outer layer of each substrate. When the thickness of the composite substrate was reduced to 72 mu m, the cubic texture could still reach 97.3% by using electron backscatter diffraction. Moreover, its saturation magnetization only reached 2.3 (emu/g). Finally, the cubic texture of composite substrates was found to vary in thickness thinning because the grain growth mechanism between the inner and outer layers is different. The inner layer defect has a "pin" effect on grain boundary migration, and in the outer layer, the cubic grain grows more easily to the surface and along the rolling direction. However, the formation of cubic-oriented grains is hindered by the twin defects in the inner layer.

摘要 ：
In this work, a series of studies have been carried out on ultra-thin Ni-5at%W (Ni5W) alloy substrates used for the coated conductors. The ultra-thin Ni5W alloy substrate can be fabricated for the large square REBCO film with a size of over 40 mm x 40 mm, which is normally used in scenarios to support a magnetic field in a specific area. To obtain a stronger recrystallized cubic texture, the intermediate annealing was added to optimize the rolling texture during the rolling process of the Ni5W alloy substrate. A typical copper-type rolling texture was obtained in the substrate which intermediate annealed at 96.25%, and the cube texture reached 97.6% after annealing recrystallization. Moreover, The deformation and recrystallization of 40 & mu;m thick Ni-5at%W (Ni5W) alloy thin substrates were investigated by the quasi-in situ method. The fabrication of ultra-thin Ni5W substrates increases the potential of miniaturizing lightweight coated conductors, which helps to further promote and accelerate the manufacturing process of the entire coated conductor strip.

摘要 ：
Face-centered cubic (FCC) metals were subjected to heavy rolling and two-step recrystallization annealing to form sharp cubic textures. The traditional theory states that the formation of recrystallized cubic-oriented grains originates from rolling cube grains. However, in our study, the Ni8W alloy underwent severe deformation during rolling, forming a typical brass-type rolling texture with almost no cubic-oriented grains. The quasi-3D electron backscatter diffraction results indicated that the newly generated cubic grains were not necessarily adjacent to the rolling cubic grains. Instead of growing from excited rolling cube grains, we found newly oriented recrystallized cubic grains generated from twin growth. Initially, most recrystallized grains undergo grain boundary migration or merging during low-temperature recrystallization annealing. Under such conditions, the initial recrystallized grains maintained the same orientation as the original matrix. However, it is also possible that the initially newly oriented recrystallized grains were generated through twinning. The {221}<122> orientation grains can cause cubic orientation by Sigma 3 boundaries. This twinning process reveals another pathway for generating initially recrystallized cubic grains in highly deformed FCC alloys. The recrystallized cubic-oriented grains ultimately evolved into cubic textures owing to their growth advantages, as described by the traditional theory. This discovery solves the puzzle of the recrystallization nucleation mechanism for cubic-oriented grains. It can help us better understand the evolution of the recrystallized cubic texture in heavily deformed FCC alloys.

摘要 ：
This study investigates crystal orientation evolution at microscopic level, and changes in the superconducting properties at macroscopic level of rare-earth-barium-copper-oxide (REBCO) superconductor tape under severe deformation. At the microscopic level, in-situ electron backscatter diffraction is used for real-time observation of the crystal orientation evolution during the entire tensile process. At the macroscopic level, the critical current (Ic) value and Ic angle dependence performance are systematically measured under different applied tensile stresses. By comparing the microscopic and macroscopic results, the synergetic evolution mechanism between them is successfully established. Stress at the initial descent point of the Ic value excellently fits the one where the (001)[100] orientation sharply decreases, thereby revealing the real Ic degradation mechanism of REBCO tapes. The application of a moderate applied tensile stress can increase the in-field Ic value and pinning force because new generated defects and strains act as pinning centers. A higher tensile stress can destroy the biaxial texture of the REBCO layer and become a significant barrier to the supercurrent flow. This research elucidates the REBCO degradation mechanism and may assist manufacturers in improving the electromechanical properties of commercial REBCO tape.

摘要 ：
Doping of nanoparticles is one of the effective methods in order to obtain nanocomposite thin films with significantly improved performance. A complete understanding of nucleation and growth mechanism for nanosized doped particles and the orientation relationship between the particles and matrix material is essentially important for the enhanced functional properties of nanocomposite films. In this study, a two-dimensional X-ray diffraction (2D-XRD) technique was utilized to detect the orientation and phase evolution of Ba2YNbO6 (BYNO) doped particles within YBa2Cu3O7-delta (YBCO). The textured and untextured information about the doped particles was extensively visualized via 2D-XRD spots and rings in comparison to 1D-XRD analysis. A systematic investigation of the nucleation and growth mechanism for the BYNO-doped YBCO nanocomposite film revealed the same orientation for BYNO particles near the LaAlO3 (LAO) substrate, whereas the rest of the particles were detected with random orientation. The higher isotropic J(c) with increased random orientation of the BYNO particles contributed significantly towards the improved superconducting properties of the thin films. Finally, a rich nucleation and growth model for the BYNO-doped YBCO nanocomposite film was established. This study aimed to analyze the orientation of the doped BYNO nanoparticles during the nucleation and growth of the YBCO film, with the main focus on demonstrating double perovskite-structured nanoparticles.

摘要 ：
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 deformation, recrystallization and grain growth. A typical copper-type rolling texture, mainly consisting of components of S, copper and brass orientations, is obtained after heavy cold rolling. The fraction of rolling texture is slightly strengthened during recovery and then strongly reduced during recrystallization process. The cube texture is formed by consuming the rolling texture components during the discontinuous recrystallization process. The cube grains have a size advantage with respect to the non-cube grains. A strong cube-textured Ni5W alloy substrate with cube texture area fraction of 98.2 % (<10 degrees) is obtained after annealing at 1050 degrees C for 1 h. The full width half maximum (FWHM) values for the X-ray (111) phi-scan and the (002) omega-scan of this substrate are 5.84 degrees and 4.76 degrees, respectively. Furthermore, the area fraction of {001} < 110 & rang; orientation of the epitaxially grown La2Zr2O7 buffer layer is 97.1 % (<10 degrees), and the FWHM values of (111) phi-scan and (002) omega-scan are 5.22 degrees and 5.00 degrees, respectively.
