Abstract: A composite material has a plate shape and has a first surface and a second surface. The second surface is opposite to the first surface. The composite material includes a plurality of first layers and at least one second layer. The first layers and the second layer are alternately layered along a thickness direction of the composite material such that the first layers are located at the first surface and the second surface. Each of the first layers is a layer including copper. The second layer is a layer of a molybdenum powder compact impregnated with copper. A compressive residual stress of 50 MPa or less acts on each of the first layer located at the first surface and the first layer located at the second surface.

Abstract: A composite material includes a plurality of first layers and a plurality of second layers. The total number of the first and second layers is 5 or more. The first and second layers are stacked alternately in the thickness direction of the composite material, such that the first layer is located at each of the first and second surfaces. The first layers are formed from a metal material containing copper as a main component. The second layer includes a molybdenum plate and a coper filler. The molybdenum plate has first and second faces that are each an end face in the thickness direction, and a plurality of openings extending through the molybdenum plate from the first face to the second face.

Abstract: The present invention provides a powder for a magnet which can form a rare earth magnet having excellent magnetic characteristics and which has excellent moldability, a method for producing the powder for a magnet, a powder compact, and a rare earth-iron-boron-based alloy material.Magnetic particles constituting a powder for a magnet each include a structure in which a particle of a phase 3 of a hydrogen compound of a rare earth element is dispersed in a phase 2 of an iron-containing material. Since the phase 2 of the iron-containing material is uniformly present in each of the magnetic particles 1, the powder has excellent moldability and easily increases the density of a powder compact 4. The powder for a magnet can be produced by heat-treating a powder of a rare earth-iron-boron-based alloy (R—Fe—B-based alloy) in a hydrogen atmosphere at a temperature equal to or higher than the disproportionation temperature of the R—Fe—B-based alloy to separate the powder into the rare earth element and the iron-containing material and to produce the hydrogen compound of the rare earth element. The powder compact 4 is produced by compacting the powder for a magnet. The powder compact 4 is heat-treated in a vacuum to produce a R—Fe—B-based alloy material 5, and the R—Fe—B-based alloy 5 is magnetized to produce a R—Fe—B-based alloy magnet 6.
