Abstract:This work aims to study the influence of hot-pressing (HP) sintering conditions (temperature and pressure) on Inconel 718 (Inc718) powders densification, microstructural, fracture mode and hardness properties. The sintering conditions included temperatures of 1000, 1068 and 1150 ºC and pressures of 50 and 60 MPa for a dwell time of 60 min. Fracture mode and the grain morphology were assessed by scanning electron microscopy (SEM). The grain size (GS) of the compacts increased with increasing HPed temperature an… Show more
