摘要:
回火脆化是加氢反应器21/4Cr-1Mo钢长期服役后的主要损伤之一,准确地预测在役材料的回火脆化程度,对加氢反应器长期使用后的安全性评价具有重要意义.综述并评价了国外对21/4Cr-1Mo钢长期服役后脆化程度的预测方法,主要包括由J系数预测长期脆化后的韧脆转变温度(FATT),以及在FATT预测基础上建立对材料断裂韧性的估算方法.

摘要:
对运行10 a的3Cr1Mo1/4V钢制加氢反应器内试块取样进行了脱脆热处理,与未热处理(脆化态)试样在不同温度下进行了小冲杆试验和夏比冲击试验,提出了以断裂能与最大载荷的比值(ESP/Fm)作为确定小冲杆试验韧脆转变温度的方法,得到韧脆转变温度及其增量,并与夏比冲击试验结果进行了对比.结果表明:小冲杆试验得到的ESP/Fm-温度曲线与夏比冲击试验得到的冲击功-温度曲线具有相同的变化趋势;与断裂能相比,ESP/Fm可以更好地表征材料的韧脆状态;以ESP/Fm稳定值的60%对应的温度作为韧脆转变温度,得到的韧脆转变温度增量与由夏比冲击试验得到的近似相等,小冲杆试验可以用来评价3Cr1Mo1/4V钢的回火脆性.%The de-embrittlement heat treatment was conducted on specimens sampled from the tested block in a 3Cr1Mo1/4V steel hydrogenation reactor, which had runned for 10 a.And the small punch test and Charpy impact test were carried out on the de-embrittled specimens and non-heat treated (namely embrittled) specimens at different temperatures.A method using the ratio of fracture energy to maximum load (ESP/Fm) to determine the ductile-brittle transition temperature of small puch test was proposed.The ductile-brittle transition temperatures and the increments were obtained and compared with those from Charpy impact test.The results show that the changing trend of ESP/Fm-temperature curves obtained from small punch test had the same trend as the impact energy-temperature curves from Charpy impact test.Comparing to the fracture energy, ESP/Fm can present the ductile to brittle state better.Using the temperature corresponding to 60% of stabilized ESP/Fm as the ductile-brittle transition temperature, the obtained ductile-brittle transition temperature increment was nearly equal to that obtained by Charpy impact test.The small punch test can evaluate the temper-embrittlement of 3Cr1Mo1/4V steel.

摘要:
应用俄歇电子能谱实验及晶界偏聚理论分析了应力、氢、应力与氢联合作用对加氢反应器母材2.25Cr-1Mo钢的回火脆化影响以及三者之间的关系.实验结果表明,应力对2.25Cr-1Mo钢回火脆化具有一定的抑制作用,而氢对回火脆化具有促进作用,随着回火脆化程度的增加,应力、氢对回火脆化的影响逐渐增强;应力与氢对回火脆化的影响机理是降低或增加了杂质原子P晶界偏聚量,二者联合作用下2.25Cr-1Mo钢的回火脆化程度近似等于应力与氢单独作用引起回火脆化度的改变量的线性叠加.%The effect of stress and hydrogen, and the combined effect of stress and hydrogen on temper embrittlement of 2.25Cr-1Mo steel used in hydrogenation reactor were analyzed by Auger electron spectrometer testing and the grain boundary segregation theory, as well as their relationship.The experimental results indicate that stress restrains temper embrittlement of 2.25Cr-1Mo steel, but hydrogen promote it, and the influence strengthens gradually with the degree of temper embrittlement increase.The effect mechanism of stress and hydrogen on the temper embrittlement is that reduces or increases the grain boundary of impurity element P, and the temper embrittlement degree of 2.25Cr-1Mo steel on the combined effect of stress and hydrogen approximately equals to the linear superposition of the effect of stress and hydrogen alone.

摘要:
厚板14Cr1MoR封头通常采用热压成型,容易产生回火脆化,降低材料韧性.通过对模拟14Cr1MoR拼焊封头的试板进行正火(940°C,保温2 h)后加速冷却处理、回火热处理[(710±20°C),保温时间3 h]及焊后消应力热处理[(670±20°C),保温时间3.2h],从理论上计算出该热处理工艺回火参数[P]在最佳值范围内;通过力学性能试验结果显示,在该热处理工艺下得到的各项力学性能符合标准要求,强韧性配合良好,说明该热处理工艺合理,有效解决了14Cr1MoR热压成型过程中材料的回火脆化问题.

摘要:
Test study of temper embrittlement tendency for welding joint of 2Cr-1Mo steel is carried out using step cooling test method .The results show that , due to the tendency of temper embrittlement of weld metal , the toughness of the heat affected zone of test welded joint is higher than that of heat affected zone .Because the phosphorus content in the weld and base material is lower , so phosphorus segregation effect on temper embrittlement tendency is smaller , while the affect of structure on tough-ness and embrittlement is si gnifican .%采用步冷试验法对21/4Cr-1Mo钢焊接接头的回火脆化倾向性进行评定试验。结果表明,由于焊缝、焊缝金属的回火脆化倾向性,试验焊接接头焊接热影响区的韧性高于焊接热影响区。由于焊缝和母材的磷含量较低,磷偏聚对回火脆化倾向性的影响较小,而组织结构对韧性和回火脆化倾向性的影响较大。

摘要:
本文通过对经7年服役的加氢裂化反应器DC102在役试块的解剖试验研究,了解了加氢反应器DC102工况对2.25Cr1Mo材料的老化,试验结果表明,长期服役对母材及焊缝的拉伸性能的影响不大,而对材料冲击性能的影响较明显.这表明经长期高温临氢服役,材料发生了脆化,并且焊缝金属的脆化程度高于母材.经脱脆处理,冲击性能基本恢复,因此材料的老化是由于高温回火引起的.
