Microstructural evaluation of nuclear grade titanium stabilized stainless steel fuel claddings

Original language description

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
