Patent number: 7776449Abstract: A composite article that can be used as a substrate for coated conductors is disclosed. The composite substrate has at least three layers in which one or more inner layers of Ni—W alloys with 9 at. %-13 at. % W and two outer layers of Ni—W alloys with 3 at. %-9 at. % W. The content of W element gradually decreases from the inner layers to the outer layers. The composite substrate can be prepared using a process of designing and sintering composite ingot, rolling composite ingot and then annealing composite substrate. The composite substrate have a dominant cube texture on the outer layer of the whole substrate which have a weaker magnetism and higher strength than that of a single Ni-5 at. % W alloy substrate.Type: GrantFiled: June 5, 2009Date of Patent: August 17, 2010Assignee: Beijing University of TechnologyInventors: Hongli Suo, Min Liu, Yue Zhao, Meiling Zhou, Lin Ma, Tieyong Zuo

Patent number: 7722804Abstract: In a method of manufacturing a pressed scandate dispenser cathode, firstly, scandium nitrate, barium nitrate, calcium nitrate, aluminum nitrate and ammonium metatungstate (AMT) are dissolved in de-ionized water, respectively, and then mixed with a solution of a cross-link agent such as citric acid and H2O2. After water bathing, the mixed aqueous solution turns into gel, and the powders are obtained after the gel calcination. Secondly, the calcined powders are reduced by hydrogen. Finally, the reduced powders are pressed into shapes and then sintered in the furnace with the atmosphere of hydrogen or by Spark Plasma Sintering (SPS 3.202-MK-V) in vacuum.Type: GrantFiled: August 8, 2007Date of Patent: May 25, 2010Assignee: Beijing University of TechnologyInventors: Jinshu Wang, Wei Liu, Meiling Zhou, Yiman Wang, Hongyi Li, Tieyong Zuo
