Microstructural Material Analysis of Superalloy INCONEL 792-5A after High Temperature Exposition

Popis výsledku v původním jazyce

The paper is oriented on structural-material analysis of cast nickel superalloy of the type INCONEL 792-5A after long-term annealing at the temperature 900 st. C. From the viewpoint of practical exploitation this represents the upper limit of efficient use. Importance of solution consists in the fact that higher level of alloying of this type of superalloy has higher level of segregation activity. This fact can lead at exploitation to development of specific microsegregation processes related to precipitation process and with formation either of carbidic phases, or some variants of intermetallic phases, e.g. of the type ´ - (Ni3Ti,Al). In our case we applied with long-term exposition time, which comprises annealing at the temperature mentioned above for 1000 and 10 000 hours. For all practical purposes this represents conditions, which have undoubtedly response from technological practice viewpoint and can contribute both to more objective evaluation of service life of the relevant cas
