| Abstract Scope |
The reduction of quantity of destructive tests on castings for aircraft engines in development process become very important issue in fast process implementation. The aim is to maintain high product quality using minimum time for development, especially when parts are needed
for new engine tests, while no hard tooling is available. Computed tomography (CT) as relatively fast, however still not cheap method, can support new products implementation. Thanks to using CT, it is possible to define in short time dimensions, including wall thickness, internal features for complicated cored castings, as well as determine discontinuity of the material such as porosity. To be able to quantify it, correlation between image and real parts from examined alloy have to be known. The polycrystalline turbine blades and multi vane segments made from nickel-base superalloys are subject of the study. CT tests were performed using various tomography systems to obtain desirable effects. |
