Abstract
(EN)
Provided is a powder metallurgy alloy steel powder which exhibits excellent compressibility and is capable of obtaining a sintered component having high strength as sintered, without containing Ni, which is expensive, or Cr and Mn, which easily oxidize. A powder metallurgy alloy steel powder having a component composition containing 0.5-2.0 mass% of Mo and 1.0-8.0 mass% of Cu with the remainder comprising Fe and inevitable impurities, the powder metallurgy alloy steel powder also having a microstructure in which the percentage by volume of an FCC phase is 0.5-10.0%.
