Abstract��The fine structure of high strength ULCB steel were investigated.The results indicated that the ideal micro�� structure of high strength ULCB steel is consists of carbide��free bainite, lath martensite and lower bainite, the microstructure strengthing(including fine strengthing) is the main strengthing mechanism, while the content of vanadium is low, the precipitation strengthing of vanadium isn��t easy obtained in high strength ULCB steel.
