Abstract Scope |
The evaluation of machining deformation on critical aerospace components is currently conducted by destructive testing that is laborious and offers limited insight into machining deformation. Current work aims to establish an X-ray diffraction method as a technique to evaluate the deformation from machining, with new information enabling holistic understanding of the deformation. Grazing Incidence methodologies are applied to machined surfaces to demonstrate the effectiveness of this technique, by altering the penetration of the X-rays into the surface to extract peak broadening data and create a true depth deformation profile. Deformation is analysed in terms of inter-granular and intra-granular strain along with precipitate phase behaviour with the aim that the extent of deformation can be quantified. Results offer insights for the development of improved machining conditions, whilst demonstrating the feasibility of the techniques as non-destructive evaluation tools.
