Microstructure Fining Theory of Low- carbon Bainitic Steel,nt result of the social need and the development of the modern metallurgy technology in recent 30 years. Due to the sharp reduction of the carbon content in the steel, the disadvantageous effects of the carbon on the toughness of the bainite microstructure is eliminated completely, and the fine bain

Compared with ordinary structure steel, ultra-high strength low alloy (UHSLA) steel has higher tensile strength (R.≥1500 MPa) but lower toughness. Because of low alloy elements, simple hot working process and relative low cost, UHSLA is widely used in spaceflight, aviation and conventional
