Microstructural Analysis of a Cast Variant of Nickel Superalloy INCONEL 738 LC after High Temperature Exposition
Original language description
Alloys of INCONEL type (hereinafter IN) play an important role among the superalloys used for already known components of aircraft engines, gas turbines and turbo blowers. It is a piece of material, which is alloyed in a complex manner on the basis of Cr-Al-Mo-Ti-Nb-Zr. In the presented work it was made a detailed microstructural analysis of cast nickel superalloy IN 738LC. The analysis was made on the sample in its initial state after annealing to the required quality by the mode 1120oC/2h/air + 845oC/24h/air, and subsequently on the samples after long term exploitation at the temperature of 850oC for a range of 100 ? 10 000 hours. A higher alloying level of the investigated superalloy shows a higher level of segregation activity. It can lead at exploitation to the development of specific microsegregation processes connected with a possible precipitation process and with the creation of either carbidic phases or some variants of intermetallic phases.
