    • 摘要: 铁、碳合金分为钢和生铁两大类。钢是含碳量为0.03%~2%的铁碳合金,含碳量2%~4.3%的铁碳合金称为生铁。钢和铁的区别完全由其内部的元素结构所决定。加入了锰元素的铁碳合金是锰钢,加入了硅元素的铁碳合金称为硅钢。锰钢、硅钢和普通碳钢的区别也完全由其内部的元素结构所决定。

    • 摘要: 运用Gleeble-3500热力模拟试验机对700~1200°C温度范围内高锰钢Mn13单独加入钛(质量分数0.10%)、复合添加钛(质量分数0.11%)和钒(质量分数0.20%)后的高温热延性进行测试.采用扫描电镜和X射线能谱分析仪对不同温度下拉伸断裂后试样的断口形貌以及断口处的析出粒子进行了分析.温度-断面收缩率曲线表明在高锰钢中加入0.10%钛后,其断面收缩率出现了一定程度的下降,这表明钛的加入恶化了高锰钢的热延性;在此基础上加入0.20%钒,高锰钢的热延性出现了进一步的下降,即钛和钒的复合加入严重恶化了高锰钢的热延性.利用Thermo-Calc热力学计算软件对单独含钛以及复合含钛钒的高锰钢在700~1600°C存在的平衡析出相进行了计算,计算结果表明Ti(C,N)的平衡析出温度均约为1499°C,远大于其液相线温度,这说明Ti(C,N)在高锰钢的液相中就可以开始析出.扫描电镜-能谱分析结果表明在奥氏体晶界以及三叉晶界处存在大量的Ti(C,N)和(Ti,V)C粒子,这些粒子的出现抑制了动态再结晶的发生,并且加速了晶界附近裂纹的扩展.%The influence of Ti(mass fraction 0.10%)and the joint additions of Ti(mass fraction 0.11%)and V(mass fraction 0.20%)on the hot ductility of as-cast high manganese austenitic steels were studied using a Gleeble-3500 thermo-mechanical simulator over a temperature range of 700 to 1200°C.Fracture surfaces and particles precipitated at different testing temperatures were investigated via scanning electron microscopy(SEM)and X-ray energy dispersive spectrometry(EDS).The hot ductility curves as a function of temperature of high-Mn austenitic steels showed that Ti addition leads to loss of ductility in almost the entire testing temperature range.Moreover,the joint additions of Ti and V do not exhibit any improvement in the hot ductility,resulting in relatively poor hot ductility behavior.The phase diagrams of precipitates in Ti-and Ti-V-bearing high-Mn austenitic steels in the temperature range of 700 to 1600°C were calculated via Thermo-Calc commercial software.The calculation results show that Ti(C,N)in Ti-bearing high-Mn steel precipitates at 1499°C,which is much higher than its liquidus temperature.This illustrates that Ti(C,N)particles form in the liquid steel.SEM-EDS results show that Ti(C,N)and(Ti,V)C particles form along the austenitic grain boundaries and the triple junction.These particles retard the occurrence of dynamic recrystallization and accelerate the extension of cracks near the grain boundaries.

    • 摘要: 利用数值方法和高温实验研究了锰钢凝固过程中MnS夹杂物的析出行为.结果表明,对MnS夹杂物析出温度的影响较大的元素次序为Mn、C、Si,在实际生产中对20Mn钢碳含量和硅含量要实行下限控制,可有效抑制MnS夹杂物析出;随着含碳量的增加,锰钢中液相线、固相线和MnS夹杂物的析出温度均逐渐降低;当碳元素从0.13%增加到0.6%时,固相线与MnS夹杂物析出温度的差值逐渐增大;当硅元素从0.05%增加到0.45%时,固相线温度由1459°C降低至1449°C,MnS的析出温度由1462°C降低至1452°C;随着含碳量的增加,锰钢中球状MnS夹杂物的比例逐渐降低,而条状MnS夹杂物的比例逐渐升高.

    • 摘要: 为了研究含纳米 CaCO3的镁钙质中间包涂料在冶炼过程中对钢水中 Mn、C 和总氧含量的影响,按90%(w)电熔镁砂和10%(w)纳米 CaCO3并外加2%(w)的 SiO2微粉制成镁钙中间包涂料,并浇注成坩埚试样,自然养护24 h 后于200°C下烘烤24 h,然后将盛有锰钢的镁钙质坩埚放入感应炉中,抽真空后通入氩气并保持氩气流动,随后将炉温升至1100°C保温50 min,再继续升温至1600°C使钢样熔化,然后每隔一段时间对钢水取样,检测钢样的 Mn、C 和总氧含量,同时对试验后坩埚制样进行电镜和能谱分析。结果表明:在冶炼过程中,钢水中 Mn、C 含量降低,总氧含量增加,这与纳米 CaCO3分解产生的 CO2与钢中 Mn、C 元素的反应有关。%In order to investigate the influence of nano-CaCO3 containing MgO-CaO coatings for tundish on Mn,C and total oxygen contents of Mn steel,MgO-CaO crucible specimens were prepared casting the mixture of 90 mass% fused magnesia and 10 mass% nano-CaCO3 ,extra 2 mass% SiO2 micropowder,nat-ural curing for 24 h and then baking at 200 °C for 24 h.The crucible specimens with Mn steel were trans-ferred in an induction furnace.After vacuuming,blowing the flowing argon atmosphere,the furnace was heated to 1 100 °C and held for 50 min firstly and then heated to 1 600 °C till the steel was melted.The mol-ten steel was sampled at regular intervals,the Mn,C and total oxygen contents were determined,and the crucible after test was investigated by SEM and EDS.The results show that Mn and C contents in molten steel decrease,and the total oxygen content increases,due to the interactions between Mn,C and CO2 gas from the decomposition of nano-CaCO3 .

    • 摘要: The static tensile behaviors of Fe-22Mn-0. 7C TWIP steel and Q235 steel between 700°C and 1300°C were investiga-ted by Gleeble-1500 thermo-mechanical simulator. The microstructure characteristic and fracture morphology were observed by optical microscopy, scanning electron microscopy, energy dispersive spectrometry and electron probe micro-analysis. The hot ductility and influenced mechanism were revealed based on the discussion of chemical composition, matrix phase volume fraction, grain size and solidification defects. It is found that the TWIP steel has a reduction in area lower than 40% in the temperature range of 700°C to 1250°C, but its tensile strength is higher than that of Q235 steel. Fractographic results manifest intergranular fracture for the TWIP steel. Grain refinement and microsegregation descending in the TWIP steel are beneficial to increasing the hot ductility due to the improvement of matrix homogeneity. Besides, the tensile strength and reduction in area of the TWIP steel increase with increasing strain rate.%基于Gleeble-1500热力模拟试验机测定了Fe-22Mn-0.7C TWIP钢和Q235钢700~1300益范围内的静态拉伸行为.采用光学显微镜、扫描电子显微镜、能谱仪、电子探针微区分析等技术表征两钢种不同温度下的变形特征和断口形貌.通过分析基体化学成分、相体积分数、晶粒尺寸、凝固缺陷等因素探讨TWIP钢铸态热塑性的变化规律及其影响机制.研究结果表明,Fe-22Mn-0.7C TWIP钢700~1250益范围内的铸态抗拉强度高于Q235,而其断面收缩率低于40%,且断口均以沿枝晶间断裂方式为主.晶粒细化和控制溶质显微偏析有利于提高TWIP钢热塑性,与基体均质性改善有关.此外,增加应变速率TWIP钢拉伸强度和断面收缩率同时增大.

    • 摘要: 根据中锰钢热轧组织结构确立两相区奥氏体化的几何模型和初始条件,利用DICTRA动力学分析软件对中锰钢马氏体基体奥氏体化过程进行计算分析。在奥氏体化初期的形核过程中,马氏体中过饱和的碳锰元素从铁素体迅速转移到奥氏体并在相界面奥氏体一侧聚集。后续的相变过程中,碳在奥氏体中快速均化,但锰在相界面奥氏体一侧的聚集加剧。相变初期奥氏体界面推移速度比中后期高出若干个数量级,但随时间推移迅速衰减。相变初期相界面推移是碳扩散主导,相变后期界面推移受到锰在奥氏体中扩散速度制约。温度升高可显著提高相界面推移速度。达到相同数量奥氏体的情况下,低温长时退火有利于锰从铁素体向奥氏体转移并提高其在奥氏体中的富集度,从而提高奥氏体的稳定性。%According to the hot-rolled microstructure of medium manganese steel, a geometry model and initial conditions of inter-critical austenitization were established, and the DICTRA dynamic analysis software was used to calculate the austenitization on the martensitic matrix. It is found that supersaturated carbon and manganese in martensite quickly transfer from ferrite to austenite and aggregate at the austenitic side of the phase interface in the initial austenite nucleation stage. In the subsequent transformation, carbon rapidly homogenizes in austenite, but the aggregation degree of manganese in the austenitic side of the phase interface increases. The migration velocity of the austenite phase interface in the initial stage is several orders of magnitude higher than that in the middle and late stages, but rapidly decreases. The phase interface movement in the early transformation stage is dominated by carbon diffusion, but is restricted by manganese diffusion rate in austenite in the middle and late stages. Increasing the temperature can significantly improve the phase interface velocity. Under the condition of achieving the same amount of austenite, the low-temperature and longtime annealing is benefit for manganese transferring from ferrite to austenite and enriching in austenite, which will improve the stability of austenite.
