Název v původním jazyce

Comparative analysis nof microstructure and fracture surfaces of blade roots

Popis výsledku v původním jazyce

Samples of chromium stainless steel were loaded to investigate fatigue crack growth in roots of steam turbine blades. Images of the material microstructure and fracture surfaces were subjected to textural image analysis. The main steps were normalization, enhancement of fiber structures and 2D Fourier transforms. By means of analysis of spectra in the space of periods, characteristic dimensions of both image sets were investigated. The locations of three peaks of spectral functions are vera close in both image sets. It may be concluded that the material microstructure is projected onto the morphology of fracture surfaces much more than was expected.
