Abstract (en)
[origin: US2020024691A1] A metal member related to the present invention is provided with crystal grains of a metal and a granular reinforcing substance formed at boundaries of the crystal grains. The reinforcing substance includes grains of a shape with a grain area equivalent grain size larger than 1/100 of a grain area equivalent grain size of the crystal grains. The granular reinforcing substance preferably includes grains with a grain area equivalent grain size smaller than ⅕ of the grain area equivalent grain size of the crystal grains. Additionally, the granular reinforcing substance preferably includes grains of a shape wherein a value of a length, in a first direction in which a length thereof is longest, divided by a length of a longest part in a direction orthogonal to the first direction is smaller than 5. A metal member with a high strength at high temperatures is manufactured by metal powder injection molding.
