Thermal fatigue of a Ni-based superalloy single crystal
Leonid Getsov, Natalia Dobina, Alexandr Rybnikov
Izvirni znanstveni članek
Oznake: thermal fatigue;single crystal;crystallographic orientation;crack;concentrator;
This paper presents a thermal-mechanical fatigue (TMF) test procedure and some results obtained in vacuum for a Ni-based superalloy single crystal. This procedure allows the monitoring of slip lines, fatigue-crack initiation and propagation until final failure. Single-crystal specimens with differen ...

The influence of long-term service exposure on the structure and properties of high-temperature steels and alloys
Alexandr Rybnikov, Leonid Getsov, Galina Pigrova, Nikolay Dashunin, Elena Manilova, Natali Mozaiskaja
Izvirni znanstveni članek
Oznake: steels and Ni superalloys;long-term exposure to high temperatures;mechanical properties;microstructure;durability and life-time prediction;
The results of studies on the mechanical properties, long-term durability, thermal fatigue resistance and microstructure of metal blades made from various steels and Ni-based superalloys after long-term (up to 100,000 h) main-gas-line exposure conditions are presented. The data were developed and th ...

A new method for determining the remaining lifetime of coated gas-turbine blades
Leonid Getsov, Pavel Grigorevich Krukovski, Natali Mozaiskaja, Alexandr Rybnikov, K. A. Tadlja
Izvirni znanstveni članek
Oznake: Larson-Miller dependence;turbine blade;remaining lifetime;coating;diffusion;equivalent temperature;
In the course of the exploitation of gas-turbine units (GTE) their turbine blades accumulate defects. These defects result from both the static stress caused by the centrifugal forces and by the thermo-cyclic stress. Since gas turbines usually operate under variable conditions, the time of exploitat ...
