Abstract: The deformation creep characteristics of as-cast silicon particles reinforced zinc-based alloys (Si/ ZA27) were determined by high temperature creep experiments at 453K and 61.1MPa condition. The experimental results indicated that the minimum creep rate of the silicon-containing alloys are about three fifth of that of the matrix alloy(ZA27). The deformation process is mainly controlled by grain boundary sliding mechanism. Both dislocation climb and disperse silicon phase are also contributed to it. Micro-structural changes were investigated during the deformation experiments.
