摘要： The present invention relates to a Ni-based heat-resistant alloy including Ir: 5.0 mass % or more and 50.0 mass % or less, Al: 1.0 mass % or more and 8.0 mass % or less, W: 5.0 mass % or more and 25.0 mass % or less, and balance Ni, having an L12-structured γ′ phase present in the matrix, and including at least one of Zr: 0.01 mass % or more and 3.0 mase/0 or less and Hf: 0.01 mass % or more and 3.0 mass % or less. This Ni-based heat-resistant alloy has improved toughness over a conventional Ni-based heat-resistant alloy based on a Ni—Ir—Al—W-based alloy, and is also excellent in ambient-temperature strength.

摘要： The present invention provides a metal wire rod composed of iridium or an iridium alloy, wherein the number of crystal grains on any cross-section in a longitudinal direction is 2 to 20 per 0.25 mm2, and the Vickers hardness at any part is 200 Hv or more and less than 400 Hv. The iridium wire rod is a material which is produced by a μ-PD method, and has low residual stress and which has a small change in the number of crystal grains and hardness even when heated to a temperature equal to or higher than a recrystallization temperature (1200° C. to 1500° C.). The metal wire rod of the present invention is excellent in oxidative consumption resistance under a high-temperature atmosphere, and mechanical properties.

摘要： The interposer substrate is joined in an overlapping state to one or more members having a connection part at one place or more, and electrically connected to the member. The interposer substrate includes a base material having one or more connection regions corresponding to connection parts of the member to be joined. A plurality of through-holes are formed in the connection region. A segment as one unit for electrical connection is constituted by forming the plurality of through-holes adjacent to each other. One or more segments are formed in the connection region. In the through-hole are formed a through electrode and a bump with a wide width formed at an end of the through electrode. The through electrode and bump are composed of a metal powder sintered body formed by sintering a metal powder including gold or the like having a predetermined purity and average particle size.

摘要： The present invention relates to a tape material for manufacturing an ignition plug electrode, the tape material being a member for forming an electrode chip, in which a base metal layer and a precious metal layer are cladded, on a bonded region set on an electrode base material of an ignition plug, the member is in the form of a long tape in which the base metal layer being in contact with the bonded region is cladded with the precious metal layer being in contact with the base metal layer, the base metal layer has a width substantially equal to one of the longitudinal width, lateral width and diameter of the bonded region. According to the present invention, bonding between a precious metal chip and a substrate can be reliably maintained to prolong the life of an ignition plug. Accordingly, precious metals can be efficiently used to save resources.
