采用薄壁结构可以改善单晶粒RE-Ba-Cu-O块体高温超导体的本征力学性能。这是样品被熔融处理的地方，具有预定义的人工孔网络以减小有效壁厚。在这项研究中，薄壁YBCO磁盘的拉伸强度测定在室温下使用巴西试验。与传统的单晶粒YBCO盘相比，当使用纳米晶时，薄壁YBCO盘显示出高93%的平均抗拉强度。
The intrinsic mechanical properties of single- grain RE- Ba- Cu- O bulk high-temperature superconductors can be improved by employing a thin- wall geometry. This is where the samples are melt- processed with a predefined network of artificial holes to decrease the effective wall thickness. In this study, the tensile strengths of thin- wall YBCO disks were determined using the Brazilian test at room temperature. Compared with conventional single grain YBCO disks, the thin- wall YBCO disks displayed an average tensile strength that is 93% higher when the
