电子束焊GH4169合金高温裂纹尖端张开位移试验

Experimeneal research on high Temperature CTOD of electron beam welded joints of GH4169 alloy

摘要: 根据国标GB/T2358-94,对GH4169合金电子束焊接接头的高温(650℃)裂纹尖端张开位移(CTOD)进行了测试。取SE(B)试样进行三点弯曲试验,然后由所得到的650℃下母材和焊缝的P-V曲线来计算CTOD值,并对试验结果进行了讨论和总结。

Abstract: In accordance with GB/T 2358-94, CTOD (crack-tip opening diaplacement) tests were conducted at 650℃ for electron beam welded joints of GH4169 alloy. According to the requirements of the standard, the specimen was a standard SE(B) (three point bending), the results were calculated using the P-V curves of parent material and weld metal. Finally, the test results were summarized and analysed.
