The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.

亚温正火温度对40SiMnCrNiMoA的组织和硬度等性能的影响的实验研究表明，当亚温正火保温温度为760℃时，复合组织中的铁素体形态是块状，处理后的材料硬度相对较低（HRC32左右）；而当采用大于800℃温度亚温正火处理，材料硬度为HRC49左右，组织中铁素体大部分较连续地存在于原奥氏体的晶界，对材料强化不利；当40SiMnCrNiMoA钢780℃亚温正火后，硬度为HRC38左右，在以往小钎杆较长寿命所需硬度范围HRC35-40内，而组织为细条状铁素体+以板条马氏体和条状无碳贝氏体为主的复合组织，晶粒细小均匀，铁素体体积含量少于20％。

SEM and TEM observations indicate that the prior austenite deformation not only refines the allotriomorphic ferrite grain but also promotes the nucleation of intragranular ferrite, both of which in turn contribute to the refinement of granular bainite cluster including its ferrite platelets and MA islands.

SEM和TEM观察表明，奥氏体形变不仅细化仿晶界型铁素体，而且促进先共析铁素体在原奥氏体晶内形核，从而有利于细化粒状贝氏体晶团及其内部的铁素体片条和MA岛。

Moreover, its microstructural characters possess several configurations under TEM, which are (1) ferrite laths with obvious interface,(2) ferrite laths without obvious interface, but the interface can be discerned faintly from the linear arrangment of those directional islands,(3) the coexistence of ferrite laths and non--equiaxed grains. These are somewhat different from those of weld structures, which are generally thought to consist of an assemblage of interwoven ferrite laths.

管线用针状铁素体钢热轧板材中有明显界面的板条束或针状片条束；没有明显界面的板条束或针状片条束，可根据条状物或岛状物的有方向性的线状分布依稀辨别界面的存在；板条或针状片条与非等轴晶共存等多种不同形态，并不象焊接组织那样通常是单一的针状片条束或板条束形态。

Addition of minor alloying elements can fine the structure of bainitic ferrite markedly. The bainitic ferrite is composed of subunits or subchunks. The carbides with different morphologies are distributed between the laths. inside the plates and at the boundaries of subunits. There are abundant fine structures in bainitic ferrite. In the primary bainite of Cu-Zn-Al alloy there are interfacial structure ledges.

结果表明：加入微量元素可以使贝氏体铁素体组织明显细化贝氏体铁素体由亚单元或亚块组成、碳化物形貌不一，分布在条间、片内和亚块边界贝氏体铁素体内有大量的精细组织。

The results show that BS 460MPa grade reinforced bar can be produced all from Q235 or 20MnSi billet by the remained heat treatment process but the production cost of the former is lower. When the water pressure minishes, the intensities of reinforced bar reduce; the higher the temperature at the entrance of cooling bed is, the lower the intensities are. Therefore, the commendatory process parameters are that five stages coolers should be opened, water pressure should be all 1.8～2.0MPa and the temperature at the entrance of cooling bed of Q235 reinforced bar should lower than 650℃. The typical microstructure(Q235): the surface layer is tempered sorbite; the transition layer is pearlite and ferrite, and the partial ferrite is acicular; the core is pearlite and ferrite and the grain fineness is 8～10 grade. The yield strength is reduced by 10～20MPa after natural ageing and it can be simulated by artificial ageing(100℃×2h or 200℃×1h).

结果表明，Q235和20MnSi钢都可以利用余热处理工艺生产出性能合格的钢筋，但前者的生产成本较低；水压减小，钢筋强度降低，上冷床温度越高，强度越低，推荐5段水冷器全开，水压均为1.8～2.0MPa，Q235钢筋的上冷床温度应控制在650℃以下；钢筋典型的金相组织（Q235）表层为回火索氏体，过渡层为珠光体+铁素体且部分铁素体呈针状，心部为珠光体+铁素体，晶粒度8～10级；自然时效后屈服强度下降10～20MPa，用人工时效可以模拟自然时效，工艺是100℃×2h或200℃×1h。

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
