| Abstract: | The microstructuro and mechanical properties of Nb,V and Ti micro - alloyed EH40 steel plate have been observed , analyzed and studied by means of metallographic microscope , H - 800 transmission electron micro- scope and mechanical testing. The microscopic observation reveals that the microstructure of EH40 steel plate produced by TMCP is of fine and uniform composite structure with few precipitated carbide particles ,and the mechanical testing results show that the steel grade is of good comprehensive mechanical properties with impact toughness exceeding the standard requirements of classification societies. |
