| Abstract: | 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. |
