Thermodynamic analysis of inclusion control in Mg-Al-Ti system oxide metallurgy technology

  • 摘要: 开展低铝含量海工钢氧化物冶金研究,扩大海工钢成分调整范围,促进诱导针状铁素体形核的有效夹杂物生成,对改善大线能量焊接热影响区韧性具有重要应用潜力。以EH420钢为研究对象,利用FactSage热力学软件,进行钢液-夹杂物平衡热力学计算,系统分析了Mg-Al-Ti脱氧体系与氧含量耦合变化对钢中夹杂物析出类型、析出条件、析出量的影响,并设计试验进行验证,为实际大线能量焊接用EH420海工钢的目标夹杂物控制提供理论指导。结果表明,控制钢中Mg、Al、Ti含量分别在0.0020%水平、0.0080%~0.010%、0.010%~0.020%时,当T.O.含量在0.0030%水平,析出Mg-Al-Ti-O复合夹杂物+MgO夹杂物;当T.O.含量在0.0060%水平时,单独析出Mg-Al-Ti-O复合夹杂物。
