Microstructural evaluation of nuclear grade titanium stabilized stainless steel fuel claddings

Popis výsledku v původním jazyce

In this work, recently produced nuclear grade stainless steel cladding material DIN 1.4970, cold worked at 24 % and 46 % microstructural analysis was performed. In both materials, microscopic investigations revealed the presence of Ti-(C,N) precipitates at the sub-micrometre range and a few larger precipitates up to several microns. Elongated stringer-like TiC precipitates in the tube drawing direction were also revealed. Grain size was determined and a well-defined substructure was observed in Field Emission Gun Scanning Electron microscopy (FEG-SEM) and High Resolution Transmission Electron Microscopy (HR-STEM) with characteristic features as MC precipitates, twins, micro-twins, slip bands. No significant microstructural variance between the two cold worked materials was observed. Report CVŘ-1543
