EFFECT OF PARTICLE SHAPE AND SIZE ON THE COMPRESSIBILITY AND BULK PROPERTIES OF POWDERS IN POWDER METALLURGY

Popis výsledku v původním jazyce

Study of structural and mechanical properties of metal powders is necessary for improving in powder metallurgy. The procedural behavior of aluminum, copper and iron powders and their alloys is important for many industrial applications. This paper presents how the shape and size of the particles influence compressibility and flow properties of metal powders. These properties play an important role in the storage, handling, dosing and compaction in powder metallurgy processes. For the samples of aluminum, copper, iron and their mixtures has been determined particle size distribution and shape of particles thus posing its mechanical properties. The biggest irregular iron particles exhibit very low compressibility about 2 % at 15 kPa applied normal stress. Conversely the fines copper particles are the most compressible. All of the basic powders indicate low compressibility at low normal load but different mixtures show bigger compression immediately after load application.
