Patent number: 11980974Abstract: In a method for manufacturing a solder joint part, at least one of a first metal base material and a second metal base material is an alloy containing Ni in an amount of more than 0 wt % and less than 44 wt % and Cu in an amount of more than 56 wt %, and solder is a solder alloy containing Ga and inevitable impurities or a solder alloy containing Ga as a main component and having a melting point of 30° C. or lower. The method includes applying the solder to a surface of the first metal base material and placing the second metal base material on the applied solder, and heating the first and second metal base materials to a temperature of 90° C. or lower in a specified atmosphere or in a liquid to generate CuGa2 or (Cu, Ni)Ga2 between the first and second metal base materials, thereby joining the first and second metal material.Type: GrantFiled: October 31, 2019Date of Patent: May 14, 2024Assignees: Nihon Superior Co., Ltd., The University of QueenslandInventors: Kazuhiro Nogita, Stuart David Mcdonald, Shiqian Liu, Tetsuro Nishimura, Takatoshi Nishimura, Tetsuya Akaiwa

Patent number: 11141784Abstract: A range of alloys of Mg and at least one of Cu, Si, Ni and Na alloys that is particularly suitable for hydrogen storage applications. The alloys of the invention are formed into binary and ternary systems. The alloys are essentially hypoeutectic with respect to their Cu and Ni contents, where one or both of these elements are present, but range from hypoeutectic through to hypereutectic with respect to their Si content when that element is also present. The terms hypoeutectic and hypereutectic do not apply to Na if it is added to the alloy. The alloy compositions disclosed provide high performance alloys with regard to their hydrogen storage and kinetic characteristics. They are also able to be formed using conventional casting techniques which are far cheaper and more amenable to commercial use than the alternative ball-milling and rapid solidification techniques which are much more expensive and complex.Type: GrantFiled: July 25, 2016Date of Patent: October 12, 2021Assignee: HYDREXIA PTY LTD.Inventors: Andrew Charles Duguid, Kazuhiro Nogita, Xin Fu Tan, John Andrew Taylor
