| Abstract Scope |
This study evaluated the effect of applying two different regeneration heat treatments to a nickel-based alloy system, used to manufacture blades of a gas turbine. The objective of this research was to identify those parameters capable of promote the occurrence of a regenerate microstructure in a nickel-based superalloy. Because of the phenomenological complexity involved in this research, it was carried out an analysis about the occurrence of the hardening phase, gamma-prime, on a gamma matrix. Microstructural characterization techniques and image analysis were used to qualitative and quantitatively determine the occurrence of phases in the superalloy, before and after regeneration process. The average size of secondary gamma-prime phase was of 0.435, 0.293 and 0.279 µm in the superalloy without treatment and with heat treatment at two different cooling rates, respectively. Finally, they were carried out nanoindentation measurements in the specimens before and after applied heat treatments. |
