摘要： A powder material of an alloy, characterized in that it has a maximum particle size of 10 mm or less and a minimum particle size of 0.1 mm or more, and a metal or an alloy particle constituting the powder material has a maximum crystal grain diameter of 30 μm or less; and a method for producing the powder material of an alloy which comprises passing a starting raw material powder between a pair of rolls (2a), to thereby effect the plastic working of the starting raw material powder and convert a crystal grain of a metal or ally constituting the raw material powder to a grain having a finer grain diameter.
