چکیده انگلیسی
Axial fracture toughness of cold worked and stress relieved Zr-2.5Nb pressure tube material containing deuterium between 5 and 200wppm was determined as per ASTM Eâ1820-15 between 25 and 300 °C using 17 mm wide Curved Compact Tension samples. For deuterium charged materials, the variation of the fracture toughness with test temperature showed typical S curve behavior. At 25 °C, the fracture toughness dropped drastically between 5 and 30wppm of deuterium concentration and afterwards it was constant between 30 and 200wppm. Samples having similar axial split density had similar fracture toughness. The lower-shelf and upper-shelf temperature was attributed to a critical axial split density and disappearance of axial split on fracture surface, respectively.
