Collection of Replicas to Evaluate the Structural Condition of Steel after Thermal Ageing

Popis výsledku v původním jazyce

This article deals with the application of surface structure replication technique in the monitoring of steels used in VVER 440 and VVER 1000 type NPPs. Experimental samples were extracted from the primary circulation pipe made of austenitic steel 08Ch18N12T. In total, four sets were evaluated. The first of them was a segment from storage. The second of them was specimens cut off the main circulation pipeline after 28 years of operation at the Jaslovské Bohunice V1 NPP. The third and fourth were samples after artificial thermal aging at 450 °C in an atmospheric furnace. RepliSet F5 resin was used to replicate the microstructure of extracted specimens. Light and scanning electron microscopy techniques were used for replica and specimen evaluation. These analyses were supplemented by hardness measurement and EDS chemical composition analysis. The results showed a slight difference in the hardness and grain size for the AR and MCP segments. The carbide particle inclusions' size and shape were similar for all specimen sets.
