    abstract = {This study presents an experimental investigation on the effect of lubricant content and forming
temperature to the properties of green products of FeCrAl powder mass formed through warm powder
compaction route. Iron powder ASC 100.29, chromium and aluminum powder were used as a base powder along
with different weight percentage of zinc stearate (0-0.4 wt.%) as lubricant to produce green products. The base
powder and lubricant were mixed mechanically in a low speed powder mixer (30 rpm) at room temperature to
prepare the feedstock. The powder mass was subsequently compacted at 100, 150 and 200°C by applying 425
MPa of axial loading simultaneously from upward and downward directions. The as-pressed samples or better
known as green compacts were characterized for their physical and mechanical properties and their
microstructures were evaluated through Scanning Electron Microscopy (SEM). The result revealed that the
application of lubricant is vital in order to ease the ejection process and to produce defect-free green compacts
with good surface finish. The results also showed that the forming temperature of 100-150°C and a lubricant
content of 0.3 wt.% significantly influenced the properties and microstructures of green compacts.}
