Latest Patents

Dong He holds a patent titled "Method of preparing a biaxially textured composite article." This invention describes a composite article that can be utilized as a substrate for coated conductors. The composite substrate consists of at least three layers, with inner layers made of Ni-W alloys containing 9 at. % to 13 at. % W, and outer layers with 3 at. % to 9 at. % W. The design allows for a gradual decrease in the W content from the inner to the outer layers. The preparation process involves designing and sintering a composite ingot, followed by rolling and annealing to achieve the desired substrate properties. This innovative substrate exhibits a dominant cube texture on the outer layer, resulting in reduced magnetism and enhanced strength compared to a single Ni-5 at. % W alloy substrate.
