摘要：

Systematic research on developing a series of extra high strength steel plates for shipbuilding via thermomechanical control process (TMCP) is introduced. A microalloyed low carbon-equivalent SiMnCrNiCu steel was used to develop F460 steel. Ultra low carbon Cu-Ni containing steels were used to develop NV-F550, NV-F620 and NV-F690 steel plates. The effect of TMCP parameters on microstructure and properties was investigated by test-scale plant trials. Industrial production trials were conducted to verify the validity of the laboratory studies on the F460 steel. Heavy plates in 45-60 mm thickness met Det Norske Veritas NV-F460 specification. The effect of heat-input on the mechanical properties of the coarse-grained-heat-affect-zone (CGHAZ) of the advanced heavy plates was studied.
