The results showed that the hardness of CGHAZ is decreasing,bainite ferrite strip coarsens,the shape of M－A constituents transforms strip into block,its size becomes large,and its bulk extends, with increasing of t8/5.In addition austenitic,M－A constituents in γ grain boundary coarsens and manifolds with increasing of t8/5.They all deteriorate the toughness of pipeline.And the extended zone of impact fracture shows brittle.

结果表明，随着t8/5的增加，粗晶区硬度逐渐减小，贝氏体化铁素体粗化，且其间的M－A组元由条状转变为块状，平均弦长增加，体积分数增大，奥氏体晶界M－A组元增多变粗，管线钢的韧性恶化，抗裂性变差，冲击断口扩展区呈脆性断裂。

The results show that grains at core are coarser and deformation bands are observed at surface,while microstructure both at core and at surface is composed of bainitic ferrite laths with high dislocation density and interlath cementite or residual austenite.Good uniforinity in h...

结合NQP钢连续冷却时的相变特点，分析其截面硬度波动在±1.5HRC内的原因在于其有较好的贝氏体淬透性，模块整个截面上都得到了均匀的贝氏体组织，贝氏体板条宽度和位错密度的差异使得其表层硬度稍高于心部。

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.
