| Abstract: | Under industrial trial-production conditions,through reasonable design of chemical composition and technology of TMCP,heavy plate Q460 with low-carbon bainite for machinery has been developed by means of grain refinement strengthening,precipitation strengthening and bainite hardening.The thickness of the plates is between 65 mm and 80 mm,which have favorable metallographic structure and mechanical properties.Meanwhile,the cost of production has been reduced. |
