摘要： The invention has for its object the provision alloy steel powders for Cr-based high strength sintered bodies having high tensile strength, fatigue strength and toughness which are adapted for use in parts for motor vehicles and parts for OA apparatus.The composition of the alloy steel powder comprises, by wt %, not larger than 0.1% of C, not larger than 0.08% of Mn, 0.5-3% of Cr, 0.1-2% of Mo, not larger than 0.01% of S, not larger than 0.01% of P, not larger than 0.2% of O, optionally one or more of 0.2.about.2.5% Ni, 0.5.about.2.5% Cu and the balance being inevitable impurities and Fe. The sintered body has substantially the same composition provided that the content of C alone is limited to 0.2-1.2%.The manufacturing method comprises molding the above alloy steel powder, sintering the resulting green compact at a temperature of 1100.degree.-1300.degree. C. and immediately cooling at a cooling rate of 10.degree.-200.degree. C./minute. The sintered product may be further subjected to carburization and heat-treatments.

摘要： In an iron-based powder, 0.01% to 5.0% by mass of a flaky powder having an average particle size of longitudinal size of 100 or less, a thickness of 10 μm or less, and an aspect ratio (longitudinal size-to-thickness ratio) of 5 or more with respect to the iron-based mixed powder is contained, whereby the flowability of an iron-based mixed powder is increased, the density of a green compact is increased, and ejection force is greatly reduced after compaction, thereby accomplishing an increase in product quality and a reduction in production cost.
