dc.description.abstractSintering is carried out by heating the graphite mold during pressing rather than direct heating of samples by eddy currents in many sintering applications. The effect of the induction on the powder metal samples is not fully visible due to graphite mold. The aim of this study is to observe the direct effect of eddy currents to powder metal parts. For this purpose, sintering was performed in a copper coil after pressing without a mold. Pure iron powder and two different iron based powder mixtures were used. Copper was added to the iron powder for liquid phase formation, and carbon was added for the formation of alloy. Effect of sintering method, sintering duration, pre-sintering and sintering temperature were investigated. In addition, conventional sintering has also been applied for comparison. As the result of the studies it was observed that, direct heating of powder metal samples with induction generates completely different sintering kinetics. It provides better mechanical properties in shorter sintering durations only in some instances and electrical resistivity values play an important role about this. Also resistivity values can give a preliminary idea about the mechanical strength after sintering. © 2018 Elsevier B.V.
