| 摘要: |
| 初步研究了选区激光熔化成形TC4钛合金的电子束焊接性。试验采用中压电子束对4mm厚试片进行焊接。焊后采用光学显微镜、显微硬度计、拉伸试验机评价了接头的显微组织和力学性能。选区激光熔化TC4焊缝与板材焊缝类似，接头的抗拉强度为1278MPa，达到母材90%以上。 |

| Abstract: |
| In this paper, the elctron beam weldability of selective laser meltded TC4 titanium alloys was investigated preliminarily. The optical microscope, microhardness and tensile test were used in analysted the characteristic of the elctron beam welded joint. The well electron beam weldability was shown from the analysis results. The tensile strengh of selective laser melted TC4 joints was 1278MPa. |
