Stålpulver legerat med molybden för pulvermetallurgi |
摘要 |
An alloy steel powder for powder metallurgy includes an iron-based powder containing about 0.5 mass percent or less of Mn as a prealloyed element and 0.2 to about 1.5 mass percent of Mo as a prealloyed element; and a Mo-containing alloy powder bonded on the surface of the iron-based powder by diffusion bonding. In the alloy steel powder for powder metallurgy, a Mo average content [Mo]<SUB>T </SUB>(mass percent) satisfies formula 0.8>=[Mo]<SUB>T</SUB>-[Mo]<SUB>P</SUB>>=0.05, wherein the content [Mo]<SUB>P </SUB>is the above prealloyed Mo content (mass percent) in the iron-based powder. |
