| 摘 要： | 采用真空自耗电弧熔炼(VAR)工艺制备Ti-10V-2Fe-3Al铸锭,研究了熔炼电流和搅拌磁场等工艺参数对铸锭凝固行为的影响,并对真空自耗电弧熔炼过程中起弧、熔炼、补缩等阶段的凝固组织及熔池形貌进行了分析。结果表明,在未加搅拌磁场时,熔池较窄,铸锭组织粗大,而施加搅拌磁场后,熔池变宽且旋转明显,铸锭宏观组织中的晶粒变小;随熔炼电流增大,熔池加深,凝固组织中的晶粒变得粗大。

| Abstract: | Ti-10V-2Fe-3Al alloy ingots were prepared by different vacuum consumable arc remelting (VAR) processes. The effects of melting current intensity and stirring magnetic field on solidification behavior of the ingots were investigated, and molten pool profile and solidification structure at different stages, such as arc starting, melting and feeding, were analyzed. The results indicate that without stirring magnetic field, coarse grain can be observed in the ingots with a narrow molten pool, while with stirrin... |
