“…In the first phase, 16mm thick TMCP-S385 and RQT-S690 steel plates with minimum yield strengths of 385MPa and 690MPa respectively are examined. TMCP is an advanced thermo-mechanical process to produce low carbon plate steels "microalloyed" with Ti, Nb and V. The production concept of TMCP is to combine controlled hot rolling with accelerated cooling to generate a bainite and ferrite dominating microstructure [16]. By using the merits of grain refinement, precipitation hardening and low amount of transformation hardening, the TMCP enables the production of as-rolled steels (i.e.…”
