| 摘要: |
| 为解决连续化生产中钽条焊接的技术难题,在惰性气体的保护下采用电容储能式预热闪光对焊,对轧制后的4 mm×4 mm钽条进行焊接试验研究.利用金相显微镜、扫描电镜和力学性能检测设备等分析检测手段,对不同焊接顶锻力作用下的焊接区(包括热影响区)的显微组织、晶粒和晶界微区成分、硬度以及焊接区拉伸强度等进行了测试.研究表明,采用合适的闪光对焊工艺可以实现大尺寸钽条的对接,焊缝组织致密,接头具有较高的结合强度,对于大尺寸钽条无头轧制与连续拉拔技术的发展具有一定的使用价值. |

| Abstract: |
| To solve the technical problems of tantalum strip welding during continuous production,the welding experiments of rolled 4 mm×4 mm tantalum strips were conducted using capacitor discharge preheating flash butt welding under inert gas protection. Using optical microscopy,scanning electron microscope and mechanical properties testing equipment, the microstructure, grains and grain boundary compositions, hardness and tensile strength of the welding zones(including heat-affected zone)under different forging forces were tested.The bonding of large-sized tantalum butts can be achieved using appropriate flash butt welding process, with dense welding microstructure and high bonding strength. It helps tothe development ofendless rolling and continuous drawing of large-sized tantalum strips. |
