The results show that after quenched and tempered with protective coating,no elements in the protective coating are found to permeate into the matrix,but the martensite laths in welded zone and heat affected zone are refined and the dispersion of carbides in these area is increased,the sizes of the dimples in these fracture are decreased.

通常情况下，D406A钢壳体在热处理中未采用保护气氛，造成调质后壳体表面脱碳严重，使壳体强度降低。为防止或减少调质处理过程脱碳带来的不利影响，可采用保护涂料或保护气氛热处理以及真空热处理等[2]，但对于大型工件，采用保护气氛或真空热处理需要大量的设备资金投入；而采用保护涂料投入较少。

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.

Carmody said the track is a continuous welded rail, and ''heat can be a factor and cause a slight misshaping or buckling in the rail.

Carmody说，铁轨是一段段焊接起来的，因此&天热可能是一个导致铁轨轻微变形或弯曲的因素&。

The result shows that the equalmatching characteristic of 10Ni5CrMoV steel welded joint is prominent.The probability of equalmatching is 48.11%,as well as,that of undermatching and overmatching are 47.55% and 4.34%,respectively.The mean-value of strength matching coefficient is nearly higher than its lower ...

计算结果表明，10N i5CrMoV钢焊接接头的等强匹配特征明显，等强匹配概率为48.11%，低强失配和超强失配概率分别为47.55%和4.34%；强度匹配系数均值偏下限，为0.955；由于母材强度数据的标准差比焊缝要大，约为1.54倍，从而使得强度匹配系数离散度较大；此外，焊接接头强度匹配系数小于0.86的概率为2.96%，可能会导致焊接接头产生冷裂纹。
