摘要/Abstract

摘要： 为了研究不同含量混合稀土(Ce/La)对A572.Gr65钢低温冲击性能的影响,对A572.Gr65钢在-40 ℃和-60 ℃下进行低温冲击试验,并使用OM观测显微组织,利用SEM结合EDS观测夹杂物及断口形貌并检测其化学成分。结果表明,稀土可以明显变质A572.Gr65钢中夹杂物,将不规则的Al₂O₃和Al₂O₃-CaO夹杂物变质为球状稀土夹杂物;夹杂物尺寸由5 μm减小至不足2 μm。加入稀土后钢的低温冲击性能有明显提升,当稀土含量达到0.0057%时,-40 ℃冲击吸收能量由未添加稀土的317.4 J升至343.6 J,提升了8.2%;-60 ℃冲击吸收能量由未添加稀土的288.0 J升至328.1 J,提升了13.9%。

Abstract: In order to study the effect of mixed rare earth (Ce/La) with different content on the impact properties of the A572.Gr65 steel at low temperature, low temperature impact tests were conducted on A572.Gr65 steel at -40 ℃ and -60 ℃, the inclusions and fracture morphology were observed by OM and SEM combined with EDS, and the chemical composition was detected. The results show that the rare earth can significantly modify the inclusions in the A572.Gr65 steel, and the irregular-shaped Al₂O₃ and Al₂O₃-CaO inclusions are modified into spherical inclusions bearing rare earth, of which the size is reduced from 5 μm to less than 2 μm. When the rare earth content reaches 0.0057%, the impact absorbed energy of the steel at -40 ℃ increases from 317.4 J (without rare earth) to 343.6 J, which increases by 8.2%, and the impact absorbed energy at -60 ℃ increases by 13.9% from 288.0 J (without rare earth) to 328.1 J.
