对40 mm厚TC4-DT钛合金自由锻件进行焊接。通过对焊接接头显微组织分析及拉伸、冲击等测试，研究了该合金电子束焊接接头的相关性能。经研究发现：TC4-DT锻件具有良好的焊接工艺性能，焊缝为网篮组织，该合金电子束焊接接头的拉伸强度与锻件相当，但冲击韧性与锻件相比略低。
對40 mm厚TC4-DT鈦閤金自由鍛件進行銲接。通過對銲接接頭顯微組織分析及拉伸、遲擊等測試，研究瞭該閤金電子束銲接接頭的相關性能。經研究髮現：TC4-DT鍛件具有良好的銲接工藝性能，銲縫為網籃組織，該閤金電子束銲接接頭的拉伸彊度與鍛件相噹，但遲擊韌性與鍛件相比略低。

Electron beam welding ( EBW) of a 40 mm thick TC4-DT titanium alloy was carried out .The prop-erties of EBW joint for the titanium alloy were researched by means of the microstructure , tension testing , im-pact testing and so on .The results indicated that the welding performance of TC 4-DT titanium alloy was excel-lent.The EBW joint of TC4-DT titanium alloy is composed by the basketweave structure α′.Compared with the forgings, the EBW joints of TC4-DT titanium alloy had similar tension strength .The impact toughness of the EBW joints was less than that of the forgings .
