| 摘 要： | 研究了焊剂碱度对管线钢时弧焊熔敷金属显微组织和韧性的影响。结果表明：随焊剂碱度的提高，焊缝中锰、钛含量产加，而氧、硅含量降低，同时具有有利于针状铁素体形核的夹杂物尺寸和分布，促进了奥氏体晶粒内针状铁素体的形成，提高了熔敷金属的低温冲击韧性。 |
| 关 键 词： | 管线钢 焊剂碱度 针状铁素体 低温韧性 埋弧焊 熔敷金属 |

| Abstract: | The effect of flux basicity on the microstructures and toughness of SAW deposited metals on pipe line was investigated. The results showed that the contents of Mn? Ti are increased and the contents of O? Si are reduced with the increasing of flux basicity. The quantity of the inclusions with suitable size favorable to nucleation of acicular ferrite is increased, then the formation of acicular ferrite in austenite is promoted and the low temperature toughness of deposited metals is increased. |
| Keywords: | pipe line steel flux basicity acicular ferrite low temperature toughness |
