摘要
采用两种焊接规范对Ti2AlNb基合金热轧板材进行电子束焊接,并对经热处理后的接头进行室温和650℃高温拉伸试验。分析了焊缝显微组织、接头拉伸性能和断口形貌,得出了以焊接线能量较高的焊接规范焊接,接头拉伸性能较好。
The electron beam welding of Ti2AlNb based alloy is performed with two types of welding parameters, and the tensile tests of post-welded heat treatment joints are Carried out on room temperature and 650℃. The microstrucmre, tensile properties and the fractographs of joints are analyzed. The results show that better tensile properties of joints are welded with higher heat input.
