Assessment of 24% cold worked titanium stabilized austenitic stainless steel fuel cladding material properties at elevated temperatures by lateral compression testing

Original language description

In the nuclear safety, the multiple barriers is one of the most important principle. Act as the first barrier, the integrity of the cladding is a crucial issue in the related research. Concerning the mechanical properties, it has difficulty in obtaining the mechanical property along the transversal direction due to the geometry of fuel cladding. In the present study, the Ring Compression Test has been adopted. The method avoids numerous drawbacks and limitations of traditional testing approach, the simpler experimental setting and easier analysis can therefore be introduced, and could further be applied on testing the mechanically irradiated tube sections in hot cell. Candidate material in the study is Titanium stabilized 1.4970 ’15-15Ti’ stainless steel owing to its outstanding radiation resistance ability. 24% cold-worked materials were compressed at room temperature, 300 oC, 500 oC and 700 oC, respectively. Post experimentation mathematical analysis and data processing were developed to properly interpret the load-deflection curves. The premilinary results showed that the tensile strength of 24% cold work tubular smaples decreases with the increasing temperature.
