Abstract: The present invention provides a shaped component for a compressor wheel that can be used to manufacture a turbo compressor wheel which is excellent in terms of high-temperature strength, rigidity, and dynamic balance and, furthermore, has optimal performance suitable for diverse required characteristics in individual portions. In the shaped component for an aluminum alloy turbo compressor wheel of the present invention, a continuous casting rod-shaped material having a small diameter or a forging-completed material obtained by carrying out hot closed die forging on the continuous casting rod-shaped material having a small diameter is used as a material, and the continuous casting rod-shaped material or the forging-completed material has a structure in which the average numbers of grain boundaries intersected in a circumferential direction on a transverse section orthogonal to a casting direction and a forging direction are minimized in a central portion and are maximized in an outer circumferential portion, and the casting direction and the forging direction of the material are along a rotational center axis line direction of a compressor wheel.

Abstract: Provided is a method for easily manufacturing a metal-polyolefin bonded body having high bonding strength. This method for manufacturing a metallic member-resin member bonded body comprises: preparing a film that includes at least one modified polyolefin layer selected from the group consisting of a layer containing a reaction product 1 of a maleic anhydride-modified polyolefin, a bifunctional epoxy resin, and a bifunctional phenol compound, a layer containing a reaction product 2 of a maleic anhydride-modified polyolefin and a thermoplastic epoxy resin, and a layer containing a mixture of a polyolefin and a thermoplastic epoxy resin; disposing the film on at least a part of the surface of a metallic substrate so as to expose the modified polyolefin layer, thereby forming a metallic member in which a resin coating layer is laminated on the metallic substrate; and bonding a resin member onto the resin coating layer of the metallic member.
