An ultra-high strength, weldable, low alloy steel with excellent cryogenic temperature toughness in the base plate and in the heat affected zone when welded, having a tensile strength greater than 830 MPa (120 ksi) and a micro-laminate microstructure comprising austenite film layers and fine-grained martensite/lower bainite laths, is prepared by heating a steel slab comprising iron and specified weight percentages of some or all of the additives carbon, manganese, nickel, nitrogen, copper, chromium, molybdenum, silicon, niobium, vanadium, titanium, aluminum, and boron; reducing the slab to form plate in one or more passes in a temperature range in which austenite recrystallizes; finish rolling the plate in one or more passes in a temperature range below the austenite recrystallization temperature and above the Ar3 transformation temperature; quenching the finish rolled plate to a suitable Quench Stop Temperature; stopping the quenching; and either, for a period of time, holding the plate substantially isothermally at the QST or slow-cooling the plate before air cooling, or simply air cooling the plate to ambient temperature.

0前言非调质钢具有优良的使用性能和较低的生产成本，受到普遍重视。HG70钢是武钢开发的工程结构用钢，具有强度高、低温韧性好的特点。传统高强度钢一般碳当量较高，焊接性能较差。通过加入微量合金元素、采取新的控轧和调质工艺，使得HG70钢在提高强度的同时，亦保持了较高的韧性和较低的碳当量，因而从理论上讲HG70应具有较好的焊接性能，但HG70钢与HS-70焊丝的匹配情况，还有待于分析验证。

For the first time, a screw pile and pile driver system for preventing flood and rushing to deal with an emergency was manufactured. The screw piles of the system is different from screw drills used to sap, and it doesn't push soils out. Analyses, including the screw pile's structural strength analysis and the screw blade's welding analysis, were done by ANSYS, which showed that the screw pile's structural strength is enough and that the distort of the screw blade is small. Testing on the screw pile and pile driver system showed that the system performed stably and could meet the need of preventing flood and rushing to deal with an emergency. A mechanics model of interaction of a screw pile and soil was built, and expressions of torque of screw pile's cylindrical part on the condition of screw pile's crew part being driven into soil fully were gained, then the relation of the torque with screw pitch and out diameter of cylinder, which shows the torque decreases with the screw pitch increasing, and that the torque increases with the out diameter of cylinder increasing, which was according with the experiments of the screw pile's being driven into soils, and thus a screw pile with the best structure was chosen. Experiments of bionic surface showed that, on the condition of certain pressure on the surface, the protruding bionic surface can not reduce adhesion and resistance and that the corrugated bionic surface can reduce adhesion and resistance. An orthogonal experiment of the corrugated bionic surface was done with the factors including the width of protrusion, the space between two protrusions, the trolley's velocity and the vertical surface pressure and with the surface frictional coefficient as the experimental target, and some inclusions were drawn that the best combination of the factors was acquired and that the width of protrusion affected the surface frictional coefficient remarkably.

Do fill gaps in the "operation" could be first ribbon in the "loophole" in the region cut off, and then cut the ribbons,"weld" together,"welding" as long as the first band at the interface at both ends of alignment and It is a little overlap, and then use transparent tape to the inside of the two ribbons together interface adhesion; if afraid of sticky tape is not strong, you can use thin wire in the ribbon at the joint and under the edge of the seam on the edge of a needle (This does not affect the normal work of the ribbon, ribbon work, after all, the main use of the middle region).

在做补漏&手术&时，可以先将色带中有&漏洞&的区域剪掉，然后再将剪断的色带&焊接&起来，&焊接&时只要先把色带两端的接口对齐并稍微有一点重合，然后使用透明胶带将色带内侧的两个接口粘连在一起；要是怕胶带粘性不强的话，可以用细线在色带接头处的上边缘和下边缘各缝上一针(这样不影响色带正常工作的，毕竟色带工作时主要使用中间的区域)。

The results show that the plasticity zone and dynamically quiescent layer become fine equiaxed recrystallisation under the thermo-mechanical effect, the grains in the heat-affected zone grow up because of the effect of friction heat. When the rotation speed is 2 500 r/min and the welding time is 12 s, good joint is achieved, and the tensile shear strength of the joint reaches 9.24 kN. The tensile shear strength of spot increases with increasing tool rotation speed, with increasing welding time, the strength increases first, while then reduces. The microhardness of plasticity zone is high, but is slightly lower than that of the base metal, the minimum value of microhardness is in the heat affected zone. When the energy input of joint is high, the fracture type of spot is mode Ⅰ, and the tensile shear strength is high; on the contrary, when the energy input of joint is less the fracture type of spot is mode Ⅱ, and the strength is low.
