Originální abstrakt

The chemical microheterogeneity in three differently heat treated samples of the ultra-high low alloy steel was measured by means of an original method based on the space concentration distribution of 9 alloying and impurity elements. Additionally, the high resolution Auger electron spectroscopy was applied in order to analyse directly the presence of alloying elements at grain boundaries. By combination of results achieved by both experimental methods, the different fracture behaviour of investigated steel grades is explained on the bases of a dissimilar distribution of Mo, C and P at grain boundaries.
