N2 - Delubrication behavior of iron powder compacts containing zinc stearate (ZnSt) or ethylene- bisstearamide (EBS) was directly observed during sintering. First, small droplets of lubricant melt appeared scattered on the surface. Then, they gradually formed large pools, and finally vaporized. In addition, ZnSt melt more remarkably bubbled before vaporization than EBS melt. After sintering the compact containing ZnSt in nitrogen, spot stains of rough surface and concentrated zinc with the diameter of 1 mm were found on the top of their surface. It is probable that the lubricant melt inhomogeneously flew out through the easier paths in the compacts to the surface accompanied by the exhausting gas of the decomposed lubricants.
