Depending on various lubricants, the effect of compaction temperature on the ejection behavior and sintered properties was studied. Lubricants were prepared by mixing of Zn-stearate and ethylene bis stearamide (EBS) in various compositions. The iron powders blended with lubricants were compacted under the pressure of 700 MPa at various temperatures. The green compacts were sintered at 1120°C for 30 min. Microstructure, density, hardness, and transverse rupture strength of sintered materials with different lubricants were investigated in detail.}, type={Article}, title={Development of Admixed Lubricant for Warm Die and Warm Compaction of High-Density PM Iron}, URL={http://journals.pan.pl/Content/119233/PDF/AMM-2021-3-02-Byungmin%20Ahn.pdf}, doi={10.24425/amm.2021.136360}, keywords={powder metallurgy, lubricants, ejection pressure, warm die, warm compaction}, }
