摘　　要：研究了不同保温温度与保温时间对C_(p)/AZ91D复合材料微观组织的影响,并简要分析了C_(p)/AZ91D半固态组织演变的过程。结果表明在保温温度为600℃保温时间为60min时半固态组织固液比例与球化率最佳,保温温度与保温时间显著影响C_(p)/AZ91D复合材料半固态组织形貌。The effects of different holding temperatures and holding times on the micro-structure of C_(p)/AZ91D composites have been studied,and the evolution process of C_(p)/AZ91D semi-solid micro-structure has been briefly analyzed.The results show that when the holding temperature is 600℃ and the holding time is 60min,the solid-liquid ratio and spheroidization rate of the semi-solid micro-structure are the best.The holding temperature and holding time significantly affect the semi-solid microstructure of C_(p)/AZ91D composites.
