Resumo
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
(σy), 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.
