Abstract

Mechanical properties of solid oxide fuel cell glass-ceramic seal material, G18, are studied at high temperatures. Samples of G18 are aged for either 4 h or 100 h, resulting in samples with different crystallinity. Reduced modulus, hardness, and time-dependent behavior are measured by nanoindentation. The nanoindentation is performed at room temperature, 550, 650, and 750 °C, using loading rates of 5 mN s-1 and 25 mN s-1. Results show a decrease in reduced modulus with increasing temperature, with significant decrease above the glass transition temperature. Hardness generally decreases with increasing temperature, with a slight increase before Tg for the 4 h-aged sample. Dwell tests show that creep increases with increasing temperature, but decrease with further aging.
