Correspondences between Images of a Fracture Surface and Material Microstructure
Original language description
A specimen modeling welded joints in steam turbine rotor was fractured by a fatigue crack in the section of material P9 (EN12070). Fracture surface was documented by SEM, material microstructure close under it by a light microscope, both in the same magnification 500x. Images covering the whole range of crack growth were analyzed. A procedure composed of normalization, detection of fibres and 2D Fourier decomposition was used to find characteristic dimensions of image textures in both image sets. The substructure of martensitic laths and plates was found to be significantly manifested in the morphology of fracture surface. An automatic method of estimation of striation spacing was developed on the basis of directional analysis of the 2D spectra of fracture surface images.
