Effect of a deformation temperature and applied strain rate level on the deformation behavior of the 3D printed inconel 718 superalloy

Popis výsledku v původním jazyce

The Inconel 718 is high-strength, corrosion-resistant nickel-based superalloy. It is known for its excellent mechanical properties and resistance to high temperature. Determining of the deformation behaviour of materials is crucial for the appropriate use of the material for specific applications. This work investigates the effect of deformation behaviour of 3D printed Inconel 718 alloy, which has been tested over a wide range of temperatures and strain rates. Based on the experimental data obtained, it was possible to determine the peak stress levels as well as the onset of dynamic softening extra with an emphasis on the corresponding mathematical description. The experimental data revealed a minimal and maximal flow stress level of 98 MPa and 683 MPa as for the combination of 1473 K - 0.1 sMINUS SIGN 1 and 1173 K - 10 sMINUS SIGN 1, respectively. The experimental data of the course of the peak strain did not support the assumed trend and onset of dynamic recrystallization as in the calculated data.
