摘　　要：主要通过定量金相法对7种加工状态的N18锆合金第二相颗粒(SPPs)进行研究,通过统计分析计算得到第二相大小、体积分数、分布规律等结果。7种加工样品分别为:锻造开坯态、热轧态、热轧退火态、冷轧态、冷轧退火态、终轧态、终轧退火态;同时还讨论第二相在加工过程中的长大因素和控制方法以及在随后退火过程中第二相与晶界的相互作用。Second phase particles（SPPs） of N18 zirconium alloys during seven manufacturing processes were investigated by means of quantitative metallography.The manufacturing processes include ingot-breaking,hot rolling,annealing,cold rolling,annealing,final rolling,and final annealing.The results of size,volume fraction,and distribution of SPPs were obtained after the software analysis.The key factors and control methods of SPPs growth in the rolling processing and the interaction between SPPs and grain boundaries in the later annealing process were also discussed.
