摘要：
In order to strengthen and obtain the optimised processing parameters during the modified SiC nanoparticles reinforce ZA27 alloys. The present investigation deals with the effects of trace amount modified SiC nanoparticles and processing parameters on the microstructures and mechanical properties of ZA27 alloy. The results indicate that the microstructures are effectively refined by the modified SiC nanoparticles. It's likely to fade the refined effect for the modified SiC nanoparticles to raise the addition temperature, prolong the holding time, increase the pouring temperature and enhance the cooling rate. In this experiment, when the addition amount is 0.5%, the addition temperature is 680 degrees C, the holding time is 3 min, the pouring temperature is 600 degrees C and the mould is preheated at 200 degrees C, the microstructure and mechanical properties of ZA27 alloy are better. The action mechanisms of the modified SiC nanoparticles and processing parameters are also discussed.
