High temperature mechanical behavior of plasma-nitrided inconel 625 superalloy
(2017-01-01)
INCONEL 625 nickel-based superalloys present limitations for use at temperatures above 600 °C. For this reason, protective coatings can be used as barriers to avoid both nucleation and crack propagation. The aim of this ...
Experimental Investigation of Delta Phase Precipitation in Inconel 625 Superalloy Aged at 550, 625 and 725 degrees C
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2020-01-01)
The delta is an important stable phase that replaces the metastable gamma '' in the microstructure of Inconel 625 superalloy. The present work aims to investigate the kinetic of delta-phase precipitation in the microstructure ...
Isothermal short-term oxidation behavior of MAR-M246 nickel-based superalloy at 800°C and 1000°C
(2022-01-01)
Superalloys are widely employed at high temperatures for structural applications. Hence, knowledge about the oxidation of these materials is essential. However, the literature is scanty when it comes to some families of ...
