A method for synthesizing a copper-silver alloy includes an ink preparation step, a coating step, a crystal nucleus formation step and a crystal nucleus synthesis step. In the ink preparation step, a copper salt particle, an amine-based solvent, and a silver salt particle are mixed, thereby preparing a copper-silver ink. In the coating step, a member to be coated is coated with the copper-silver ink. In the crystal nucleus formation step, at least one of a crystal nucleus of copper having a crystal grain diameter of 0.2 μm or less and a crystal nucleus of silver having a crystal grain diameter of 0.2 μm or less is formed from the copper-silver ink. In the crystal nucleus synthesis step, the crystal nucleus of copper and the crystal nucleus of silver are synthesized.

A structure in which a plurality of particles each containing a hydrogen absorption metal element are arranged in a fixed member such that the plurality of particles are apart from each other. An entire surface of each of the plurality of particles is surrounded by the fixed member. The fixed member contains at least one of an oxide and a nitride.

A disc cutter for a cutting unit used in a tunnel boring machine and a method of producing the same. The disc cutter includes an annular disc body made of a metal alloy or metal matrix composite having a first side, a second side arranged substantially opposite to the first side and a radially peripheral part. At least one metal alloy, metal matrix composite or cemented carbide cutting part is mounted in and substantially encircling the radially peripheral part of the disc body, which protrudes outwardly therefrom to engage with the rock during the mining operation. The at least one cutting part is made from a material having a higher wear resistance than the material used for the disc body. A metallic interlayer is disposed between at the least one disc body and the at least one cutting part, the elements of which form the diffusion bonds.
