Abstract
This work intends to analyze the influence of the stress and temperatures used in creep mechanical tests in the types of fractures that occurred in the superalloy Inconel 718. For this, the superalloy was subjected to creep tests under the conditions 625 to 814 MPa at temperatures of 650, 675 and 700°C. After the tests, the fractured samples were cleaned on an ultrasound and subjected to microstructural analysis using the technique of scanning electron microscopy. Images were performed with different increases in order to analyze the type of fracture that occurred in the material. The elongated sample and its reduction in area were also measured in order to study the effects of different conditions used in the creep tests under material's fracture.
