Abstract

Powder compaction is a widely applied manufacturing process through transforming metal powder to solid engineering components by shaping the powder mass inside a rigid die. One of the key compaction parameters is the forming temperature which affects the mechanical properties and microstructures of the green compacts. Therefore, this paper aims to present the outcomes of an experimental investigation of iron powder compaction process at various temperatures. Iron powder ASC 100.29 was used as feedstock during the investigation. The forming temperature was ranged from 30°C to 200°C while the downward and upward simultaneous axial pressure was fixed as 380 MPa. The defect-free green compacts were characterized for their relative density, total porosity, pore size, spring-back, bending strength, electrical resistivity and hardness, while the microstructures were analyzed through scanning electron microscopy (SEM). The outcomes revealed that the green properties of powder compacts were significantly affected by the forming temperature.
