Original abstract

This paper deals with the causes of a transversal crack in a steel slab with an l300 ,l45 mm cross-section by means of results from two models. Samples were taken from and around the crack in order to analyze the concentration (chemical heterogeneity) of the selected elements. Simultaneously, the concentration of elements at the surface of the crack was measured after the crack was opened. The chemical heterogeneity of elements was analyzed by means of the JEOL JXA 8600/KEVEX analytical equipment. The measurement results were processed using mathematical statistics procedures. The results proved that there was an internal crack initiating immediately below the curve of the solid-state temperature and consecutively propagating.

Za použití numerických modelů teplotního pole a chemické heterogenity je analyzována příčina vzniku příčné trhliny v ocelové bramě 1300x145 mm. Jsou odebrány a analyzovány vzorky pro stanovení chemické heterogenity. Měření jsou zpracována statistickými metodami.
