A steel plate having a tensile strength of at least about 930 MPa (135Ksi), a toughness as measured by Charpy V-notch impact test at least about 120 joules (88 ft-lb), and a microstructure comprising at least about 90 volume percent of a mixture of fine-grained lower bainite and fine-grained lath martensite, wherein at least about 2/3 of said mixture consists of fine-grained lower bainite transformed from unrecrystallized austenite having an average grain size of less than about 10 microns and comprising iron and specified weight percentages of the additives: carbon, silicon, manganese, copper, nickel, niobium, titanium, aluminum, calcium,rare earth metals, and magnesium, is prepared by heating a steel slab to a suitable temperature; reducing the slab to form plate in one or more hot rolling passes (10) in a first temperature range in which austenite recrystallizes; further reducing said plate in one or more hot rolling passes (10) in a second temperature range in which austenite does not recrystallize, quenching (12) said plate to a suitable quench stop temperature (16); and stopping said quenching and allowing said plate to air cool (18) to ambient temperature.

It is necessary for two kinds of controlled cooling processing to possess air cooling phase to separate ferrite from austenite, and, by means of this, polygonal ferrite forms, the carbon concentration of the retained austenite untransformed increases and results in the stability of retained austenite increased.

在二种冷却方式轧后控冷的过程中，必须有一个α/γ二相分离的空冷阶段，使多边形铁素体形成，未相变奥氏体中碳浓度增高，其稳定性增强。

austenite：体

回火是将淬火钢加热到奥氏体(austenite)转变温度以下,保温1到2小时候冷却的工艺. 回火往往是与淬火向伴,并且是热处理的最后一道工序. 经过回火,钢的组织趋于稳定,淬火钢的脆性降低,韧性与塑性提高,消除或者减少淬火应力,
