Alloy powder raw material and its manufacturing method
摘要:
When starting raw material powder is passed through a pair of rolls (2a), plastic working is applied to the starting raw material powder, and the crystal grain diameter of a metal or alloy constituting a matrix of the powder particle after processed is miniaturized. According to the thus provided alloy powder raw material, the maximum size of the powder particle is not more than 10 mm and the minimum size of the powder particle is not less than 0.1 mm, and the maximum crystal grain diameter of the metal or alloy constituting the matrix of the powder particle is not more than 30 μm.
