Nickel-based superalloys have excellent properties at high temperatures, which makes them appropriate for applications such as turbocharges and aeronautic gas turbines. MAR-M246 is a superalloy developed these kinds of applications. The objective this work was to study the total replacement Ta by Nb in atomic percentage superalloy, regarding oxidation resistance. Although both elements same rol...

Abstract The planar-biaxial thermo-mechanical fatigue behavior of nickel-base superalloy Inconel 718 was studied for selected proportional loading conditions, in particular biaxial strain ratios 1.0, 0.6, and − 1.0. cyclic temperature with minimum maximum temperatures 400 °C 630 a duration 250 seconds either In-Phase or Out-of-Phase to the mechanical axes. Besides multiaxial tests, uniaxial tes...
