Sažetak (engleski)
Although construction materials are considered the most predictable components of a construction project, design and material challenges represent a major cause of productivity loss. The occurrence of non-conformities is a consequence of the very difficult quality assurance under industrial conditions, especially in the context of material processing. In this paper, non-conformities detected during the ultrasonic testing of the steel infrastructure were analysed. The investigation of non-conformity area included the chemical composition analysis, the thermodynamic calculations of the solidification sequence and metallographic analysis. The ultrasonic test results indicated the crocodile effect associated with the thermomechanical processing of steel ingots containing casting defects. This fact was supported by the results of the non-equilibrium solidification sequence. Microstructural analysis of the non-conformity area indicated the presence of non-metallic inclusions and cracks. The crack nucleation and propagation occurred during the thermo-mechanical processing. The microstructure constituents also indicated improperly performed thermo-mechanical processing. The rolling texture and acicular ferrite pointed to improperly performed normalization. The conducted research indicates the need to impose additional requirements on the microstructure of the final product, although it is not required by the EN 10025-2:2019 standard.
