摘要
对Ｎ８０套管材料的冲击转变特性与断口分离行为进行了研究．搞清了分离裂纹随试验温度的变化规律及其与冲击功的相关性．通过微观分析。
The impact transition and fracture separation behaviour have been investigated. The changing trend of separation with testing temperature and the correlation between saparation and impact energy have been revealed. The separation mechanism and causes of changing on toughness resulting from separation have been discussed by micro analysis.
