Abstract: The present invention relates to a powder material including metal particles, in which in a mass basis cumulative particle size distribution, the metal particles have a 10% particle diameter d10 of less than 16 ?m and a 90% particle diameter d90 of more than 35 ?m and when a specific energy obtained as a value yielded by dividing a flow energy measured as an energy acting on a blade spiraling upward in the powder material by a mass of the powder material is normalized with a bulk density of the powder material, a resulting value is less than 0.47 mJ·ml/g2 and relates to a producing method for the same.

Abstract: The present invention relates to a metal powder material containing: metal particles having a particle diameter d10 of 10 ?m or more and 100 ?m or less; and nanoparticles containing a metal or a metal compound, in which the particle diameter d10 is a particle diameter at which an under-sieve cumulative fraction in a mass base distribution of particle diameter reaches 10%, and the nanoparticles are adhered to or mixed with the metal particles.
