摘　　要：研究开发了120 mm高强韧特厚钢板,通过力学性能分析和断口形貌、组织观察对工业试制钢板的综合性能进行了研究。结果表明,采用NiCrMo合金系成分设计,工业试制的10CrNi5Mo特厚钢板获得了良好的综合性能,显示出了高的上平台冲击功和良好的低温韧性。In this paper,the high stength and toughness super- thick plate of 120ram has been researched and developed. Comprehensive performance of industrial trial - produce plate has been researohed by mechanical properties analysis, fracture appearance and mierostructure observation. The results show that, by NiCrMo composition design, industrial trial - produce 10CrNi5Mo super - thick plate obtains upstanding comprehensive performance and exhibits high upper Charpy impact energy and excellent low temperature toughness.
