摘要

    摘要
  • 摘要: 针对新型钢铁材料焊缝熔敷金属的韧化问题，采用直接氧化物合金化这一新型方法，通过焊接材料实现了纳米氧化物颗粒向液态熔池中的过渡，研究了纳米氧化物对低合金高强钢焊缝熔敷金属组织性能的影响. 结果表明，纳米Al2O3，TiO2和稀土氧化物的添加使焊缝中生成了大量弥散分布、尺寸为0.2～0.8 μm的细小球形复合夹杂物，有效提高了针状铁素体的形核能力，形成了大量板条束尺寸约1～2 μm、且均匀分布的针状铁素体. 纳米氧化物的添加使熔敷金属的冲击韧性显著提高，尤其是添加二氧化钛和稀土氧化物的焊缝，其-20℃冲击韧性达到了150 J/cm2以上，比无氧化物添加的焊缝冲击韧性提高67%.
    Abstract: Aimed at the improvement of mechanical properties for new generation iron and steel welds, a new method, oxide metallurgy was adopted. The adopted oxides were added into liquid welding pool through electrode and the effects on microstructure and mechanical properties were studied. The results showed that a large quantity of spherical complex inclusions with the mean size of 0.2~0.8 μm were found in Al2O3, TiO2 and Ce2O3 added weld deposits. These inclusions effectively promote the formation of acicular ferrite with mean size of 1~2 μm. The impact toughness of weld deposits increase evidently compared to that of no oxide added case, especially for TiO2 and Ce2O3 added weld deposits which have impact toughness of about 150 J/cm2 (-20℃), increasing by 67%.
