| Abstract Scope |
The geometry of the future high pressure single crystal turbine blade may contain internal walls which confer them an higher thermo-mechanical resistance. These internal walls have to be controlled by an NDT test to ensure the monocrystalline arrangement is maintained troughout the part. This is critical as the presence of internal grains can impede the part performance which may cause irreversible damage. The proposed solution is to develop a new industrial NDT system using high energy Laue transmission diffraction method which represents a technological breakthrough in the current industrial environment. A compact laboratory high energy Laue diffraction system, capable of working with actual parts and fast acquisition have been developed. Experimental diffraction image analysis is performed by an in-house indexing algorithm which takes into account the specificity of a laboratory system and make use of a reliable forward simulation model. |
