Weld residual stress distribution of GH536 superalloy with EBW measuned by Mathar method

    摘要
  • 摘要: 航空发动机许多高温合金结构需要采用电子束焊接制造,但目前对其焊后的残余应力分布状况研究较少。针对航空发动机GH536合金材料,采用小孔法对其电子束焊接试板的残余应力分布趋势进行测试研究,试验结果表明,焊缝区存在较低的应力峰值,且应力分布符合传统规律。研究旨在为航空发动机构件的电子束焊接加工制造积累经验和性能数据。

     

    Abstract: Electron beam welding is applied to manufacturing many superalloy components of aeroengine, but the researches of weld residual stress were very few for those components. In this paper, weld residual stress of GH536 superalloy components with EBW were measured by Mathar method. Test results showed that residual stress is low in the weld and its distribution accords with the traditional rules. This research can accumulate experiences and properties data for manufacturing aeroengine components with EBW.
