FH40高强船板的工艺控制及低温韧性研究

Study on Low Temperature Toughness and TMCP of High Strength Hull Structural Steel FH40

介绍TMCP（热机械控制轧制）交货状态厚规格FH40高强船体结构钢工艺控制过程。分析其成分、工艺、组织、性能之间的相互关系，探讨影响其低温韧性的主要因素。

This paper introduces TMCP （ Thermo - mechanical Controlled Processing） delivery condition of high strength hull structural steel FH40, analyzing the interrelationships of composition, process, microstructure and mechanical prop- erties. Some factors affecting the low temperature toughness have been discussed and the improvement measures are put forward.
