Microstructural Analysis of a Cast Variant of Nickel Superalloy INCONEL 738 LC after High Temperature Exposition

Popis výsledku v původním jazyce

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.
