composition were attached to alumina rods with Pt-Rh wires and mass changes were typically measured after 1, 5,
20, 40, 60, 80, and 100 cycles and then every 50 cycles using a Mettler model AG245 balance. The resulting
gravimetric data are shown in Fig. 2, which also contains data from compositions based on the phase fields
