A new, high strength (2.4 GPa) polycrystalline alumina fiber has recently been developed at 3M (trade name Nextel 610). The high temperature creep properties and creep rupture mechanisms were determined in the temperature range 900°C −1200°C. The creep rate was proportional to the cube of stress and was controlled by an interface reaction mechanism. In addition, alumina-based nanocomposite fibers containing ZrO2 and mullite second phases were synthesized and evaluated to determine whether the high temperature properties of alumina fibers could be improved by second phase additives. Nanocomposite fibers containing zirconia had creep rates similar to single phase alumina fibers, while fibers containing second phase mullite exhibited significantly lower creep rates.
