- In the present study, the production of Inconel 718 nickel based superalloy was carried out in an electric current activated sintering in open air under a uniaxial pressure of 300 MPa using Al, Ni, Fe, Cr, Ti, Co, Fe-Nb and Fe-Mo powders. This alloy was heat treated, following the conventional treatment which consists of a 1 h solution treated at 980°C, followed by air cooling and double ageing, 8 h at 720°C, furnace cooling at 55°C/h down to 620°C and ageing for 8 h. Optical and SEM examinations showed a dense microstructure with low amount of porosity. XRD studies showed the existence of the γ and MC type carbide (M atom is a Nb, Ti combination) and δ phases. The relative density of sample measured according to Archimedes' principle was 93.7%, and the microhardness of sample was about 343.8 $HV_{0.1}$.
