The creep properties of wet-processed 3 mol% Y{sub}2O{sub}3-stabilized ZrO{sub}2/Ni composites (20 and 40 vol% of nickel content) have been studied by compressive constant load tests in the temperature range 900°C - 1250°C under argon atmosphere. The microstructural characterization of these cermets has been performed using scanning and transmission electron microscopy. The composites consist of nickel particles (1μm in size) uniformly distributed throughout a fine-grained zirconia matrix (0.13μm in size). The mechanical and microstructural results indicate that the overall creep behavior of the cermets is controlled primarily by the zirconia matrix; metal additions increase the ductility of the material.
