Mechanical properties and fatigue resistance of 3D printed inconel 718 in comparison with conventional manufacture

Popis výsledku v původním jazyce

The paper contains results of the first stage of experimental programme aimed at an evaluation of microstructure, mechanical properties, fatigue durability and creep of the first batch of Inconel 718 samples manufactured using the 3D printing technology, Direct Metal Laser-Sintering (DMLS). Specimens were printed in the X position with specimen axis perpendicular to the built direction. The results, compared with specimens manufactured conventionally, were completed and discussed with analyses of damage mechanisms particularly using scanning electron microscopy. Static strength of the printed material was significantly higher in comparison with conventional material. Fatigue resistance was comparable provided that there were no microstructure defects causing premature failure. High sensitivity to sever machining was demonstrated.
