High energy white beam x-ray diffraction studies of strains in engineering materials and components

Thesis

The primary aim of this research was to develop and improve the experimental method and data interpretation for strain measurements using diffraction methods to gain a better understanding of micromechanical deformation and anisotropy of lattice strain response. Substantial part of the research was devoted to the development of the laboratory high energy X-ray diffractometer (HEXameter) for bulk residual strain evaluation.

White beam energy dispersive X-ray diffraction was chosen as...
