Properties of an atomized iron powder of branched particle shape

Conclusions The experimental atomized iron powders described combine good compactibility with high compressibility. The level of mechanical properties of parts from the experimental powders is much higher than that of parts from the control powders investigated. The optimum sintering temperature, ensuring the best combination of strength and ductility properties in parts from the experimental powders, is 1100°C. Metallographic investigations of the particle shapes of powders and of the structures of parts sintered from them have shown that, because of the well-developed particle surface of the corallike powders, the resultant materials have a fine porous structure and good mechanical properties.The authors are most grateful to S. M. Solonin for assistance with experiments and helpful discussion of results.Translated from Poroshkovaya Metallurgiya, No. 10(262), pp. 1–7, October, 1984.
