Original abstract

In the working conditions of the jet engines gas turbines of supersonic plane blades are loaded by the cycles, this process is the function of the time, temperature and stress. The blade are exposed to influence of degradable processes namely of the high-temperature corrosion, fatigue process and creep. As the result of short overloading as it happens for instance during the starts and landing, eventually in some other irregularities of the jet engine function, the increase of stress and temperature leads to the changes of microstructure and properties.

Czech abstract

Niklová superslitina Inconel 713 LC je používána k výrobě oběžných kol malých spalovacích turbin pro pomocné energetické jednotky v leteckém průmyslu. V provozních podmínkách spalovacích turbín proudových motorů jsou lopatky oběžných kol namáhány časově, teplotně a napěťově proměnnými cykly zatěžování. Během provozu jsou lopatky vystaveny řadě degradačních vlivů, zejména vysokoteplotní korozi, únavovým procesům a creepu.
