Research on Microstructure and Properties of Ti700sr High-temperature Titanium Alloy TIG Welded Joint

  • 摘要: 采用TIG焊接方法对Ti700sr高温钛合金板材进行了焊接,研究了接头的组织形貌、硬度分布及力学性能。结果表明,Ti700sr高温钛合金板材焊接后的接头成形良好,焊缝区组织由粗大的柱状晶及细长的针状α相构成,热影响区组织由细针状α和残余β相构成,热影响区析出相得到有效控制,相边界上无明显硅化物析出;焊接热影响区的硬度相对较高,焊缝的硬度相对较低;接头室温抗拉强度约为903 MPa, 700℃高温抗拉强度为397 MPa,焊缝强度低于母材的。
    Abstract: The welding of Ti700sr high-temperature titanium alloy plate was conducted with TIG technology, and the microstructure, hardness distribution and tensile properties of the welded joints were analyzed. It was confirmed that the joint was well formed after welding. The weld zone was composed of coarse columnar crystal and slender acicular α phase, the heated affected zone was composed of slender acicular α phase and residual β phase. The precipitation in HAZ was effectively controlled, and there was no obvious silicide precipitation on the phase boundary. In general, the hardness of HAZ was relatively higher and the hardness of weld low. The strength of the joint was about 903 MPa at room temperature and 397 MPa at 700 ℃. The strength of the weld was lower than that of the base metal.
