Abstract:	Shear rate, shear stress and power for mixing of semi-solid mixtures (SSMs) of ZA27 alloy and ZA27 alloy-based composites with large Al2O3 particles were investigated. Mixing was carried out using cylindrical and paddle stirrer. Mixing power was determined by electric method in the temperature range from 479 to 440 °C at constant cooling rate. Calculated values of shear rate, shear stress and mixing power for the composite (SSMs) are lower than those of ZA27 alloy in the whole range of operating temperatures.
