abstract = {The structural integrity of the sealant material is
critical for the reliability of solid oxide
fuel/electrolysis stacks. In the current study, a torsion
test is implemented to evaluate and compare its shear
strength with a partially crystallized glass sealant at
room- and operation relevant high-temperatures.
Hourglass-shaped specimens with different configurations of
hollow- and full-halves are utilized for testing. The
fracture surfaces are visualized via optical microscopy and
complementary scanning electron microscopy. In addition,
cyclic loading is used to investigate potential subcritical
crack growth effects in the sealants. Both, the specimens
with a hollow-half as well as the ones with two full-halve
steel plates yield almost the same nominal shear strengths.
The shear fracture stresses decrease with rising
temperature, while the fracture mode changes from brittle at
room temperature and 600 °C to ductile at 800 °C. The
cyclic loading condition indicates subcritical crack growth
in the sealant at 600 °C and creep associated damage at
800 °C.},
