Özet

Induction sintering provides large time and energy savings because the components heat up rapidly and the sintering time is lower than in classical sintering in a furnace. Therefore, induction sintering is an important alternative to classical sintering. In this study, mechanical properties of induction-sintered Fe-based components including Cu and carbon (graphite) were compared with those sintered in a classical furnace. For this purpose, microstructure photographs of both samples were taken. A tensile analysis of the sintered powder-metal samples was carried out with the finite-element method, and the micro-stress values were found to change depending on the amount and distribution of the porosity.
