Abstract

This study utilizes nanoindentation to investigate and measure creep properties of a barium calcium alumino-silicate glass-ceramic used for solid oxide fuel cell seals (SOFCs). Samples of the glass-ceramic seal material were aged for 5, 50, and 100 h to obtain different degrees of crystallinity. Instrumented nanoindentation was performed on the samples with different aging times at different temperatures to investigate the strain rate sensitivity during inelastic deformation. The temperature dependent behavior is important since SOFCs operate at high temperatures (800-1000 °C). Results show that the samples with higher crystallinity were more resistant to creep, and the creep compliance tended to decrease with increasing temperature, especially with further aged samples.
