Abstract
This study aims to determine some mechanical properties of an Inconel 718 aged superalloy obtained through hot tensile tests. These properties as conventional 0.2% yield strength (σv), ultimate strength (σUTS), and specific elongation assessment (εu) are important parameters in the study of the mechanical material behavior. The superalloy was subjected to hot tensile tests at 650 to 700°C and a strain rate of 0.5 mm/min according to ASTM E-8. It is used a scanning electron microscope (SEM) to obtain images of the fracture surface of the specimens. The images of the fracture surface are analyzed in order to relate the temperature of the test with the type of mechanism of fracture.
