THE INFLUENCE OF CHARACTERISTICS OF IRON POWDERS ON WARM-COMPACTED DENSITY

This paper gives a research of the influence of characteristics of iron powders on warm-compacted density.The result shows that high green density can be abtained in warm compaction process by controlling iron powder types,particle distribution, chemical content and powder micro-hardness.Following the present research results,domestic iron powder can warmly be compacted up to the density of 7.30 g/cm³.
