Intensification of Compaction and Hardening of Iron Powder Parts and Powder Steels at the Stage of Cold Molding before Sintering

Abstract:

The article presents experimental-based mathematical models for density, hardness and tensile strength of workpieces of iron-based powders, manufactured by molding with subsequent sintering. The experiment examines the powders of six brands, Russian and foreign. The diagrams show changes of the investigated values depending on brands of powders and pressures of molding compression. The impact of compaction schemes implementing significant shears between the compacted particles is estimated.
