                         elevated temperature properties, especially creep resistance. This 
                         study aimed to evaluate creep and mechanical behavior of Inconel 
                         718 superalloy. Creep tests were performed at temperature range of 
                         650 to 700 degrees C and stress range of 625 to 814 MPa. Hot 
                         tensile and oxidation tests were performed and the 
                         characterization techniques used in this study were scanning 
                         electron microscopy (SEM) for microstructural and fracture surface 
                         analysis, transmission electron microscopy (TEM) for precipitates 
                         analysis; grazing X-ray diffraction for analysis of oxide 
                         formation and Vickers microhardness. The analyze of stress 
                         exponent value (n = 36.48) and activation energy (Q(c) = 512.97 
                         kJ/mol), suggested that creep mechanism at 650 degrees C was the 
                         climb dislocation mechanism. The Inconel 718 presented ductile 
                         fracture at 650 and 700 degrees C and intergranular fracture to
